No I don't really have the answer persay:-) I do kind of have an idea and it's called optimized weighting vs a lot of wasted weight, For instance take a look at the bottom of your driver it's pointless and is wasted material and weight.

Nike has already started to hollow out their drivers and adding more wight where it's actually needed. In the future they may find a way reduce it to 100 grams optimize the weight where it's needed for faster club head speed same energy transfer and of course being the face is the same titanium and legal cor.

You realize drivers already are hollow, right?

Yes the Nike one I was depicting here,but not all of them. Sure they are tin cans but the bottom of them often has added weights and metal between the hollowness it's wasted weight tha alters cg as they say. Great clubs sure I'm just saying they can be better in design..

So your whole premise is wrong. It shows your lack of knowledge again in anything science related.

Umm, all drivers are hollow. :doh::doh:

98% of all golf drivers are not hollow duhh. Besides Nike. That bottom plate and movable  weight is probably 35 grams or more

 

See the 2 photos below? Which one would you categorize as actually being hollow vs just internally hollow?

See they are already starting to do as I say optimizing weight and removing unnecessary weight.

Are you an idiot or just like to act like one for some reason. 

:doh::doh::doh::doh::doh::doh:

Guess what, 100% of all drivers out there are hollow. There is not one driver that is 100% solid metal. 

To answer your question. They are both hollow.

The weight isn't removed. It's repositioned. That clubhead still weights in the range of 180-200 grams. It actually might weight closer to 205 grams. That driver has a D4 swing weight with a 60 gram shaft in it. That means it has substantial weight in the clubhead compared to other drivers.

You a betting man? No I'n not a scientist either are you or most people. Anyway 100 bucks say's this happens one day ok :dance: Boom I win yup pay to 

Well, let's see…

  • @jamo and @saevel25 have engineering degrees and are employed as engineers.
  • I have two degrees in the sciences (one even has the word "science" in the name), and use science every day.

So it depends on what you mean by "scientist." But by any definition, I'm much closer to being one than you.

To keep it simple for you guys yes internally hollow. Nike has taken the bottom out of it and re positioned the weight as I have explained. The idea is to re position the weight with a 100 gram head to maximize smash factor to the same as a heavier head that's it. Possible maybe maybe not? I think so you guys are getting lost in trivial matters again are not getting this at all!!. You think I'm stupid when you guys are not getting what I'm saying it's humorous. It may be possible and could be done one day. It's like im talking to 12 year old's about car mechanics and gas mileage and you spout off about how all cars have motors it won't work yada yada.. It's theoretical has nothing to do with the fact that all drivers are hollow. Nike was a depiction of how they took the bottom out of it and positioned the weight. Probably still 200 grams,but maybe it's doesn't have to be with the correct design and weight positioning.

Nike's head probably weighs the same as everyone else's.

Uh, right. It's us who is not getting it. Okay then.

Then why claim that 98% of drivers are not hollow?

Nope. It's to allow them to optimize CG location and MOI. It has nothing to do with smash factor.

Good theories are at least backed by facts, not your delusional ignorance.

Yes it does. It doesn't matter what you do. If you take the weight down you will lower the smash factor. You have yet to prove otherwise. Guess what, centuries of physics says you can't.

You fail to understand the concept of constraints. 

1. USGA limits ball speed
2. USGA limits the coefficient of restitution
3. Physics defines collisions by transfer of kinetic energy which is based on mass, velocity, and a coefficient of restitution. 

Unless you have a way of defying physics your theory fails before it gets off the ground.

Internally hollow?  C'mon Mike.

Nike didn't take the bottom out they just reduced the volume of air inside the driver head.  There's still a bottom to the Nike driver head, it's just the bottom of the cutout is closer to the top of the head.  It's called marketing, not science.

Duh-Externally hollow.

And as @Mike Boatright is demonstrating-Mentally hollow.

''A hole or depression in something definition of hollow'' Most drivers are empty inside being internally hollow vs the definition of hollow as an external empty space vs a solid exterior object and empty interior.

    • It sucks to carry around a lot of water, but ideally it should be way more than we think.  I buy those gallon jugs of water and hang them from my pushcart when I walk. I agree with the electrolytes as well. You don't just sweat out water, but you lose electrolytes as well. 
    • A 2010 study from the Journal of Strength & Conditioning Research compares the effects of different pre-round stretch routines for competitive golfers. Active Dynamic Warm-up: Swing Medicus driver, hit 3 shots each with selected clubs. Passive Static Stretches: Various athletic stretches such as hamstrings, chest stretch and reverse trunk twist. The subjects were collegiate golfers with a HDCP index of 5 or less who engaged regularly in strength and fitness routines. All golfers had two test days: one with active dynamic (AD) warmup, a second with AD followed by static stretches (SS). The results were then compared, within golfers and across golfers. For performance testing after the warmups, golfers hit three driver shots at time 0, 15, 30 and 45 minutes after the warmup. The study shows that static stretch formats produced poorer performance outcomes in the four measures shown in Table 5, which shows Time Zero results. The performance deficits under the PSS protocol decreased over time. Some suggestions on why the passive protocol was tied to lower performance than the active protocol: The passive stretches routine induced excessive range of motion,  basically producing wobbles in the golf swing. Other research indicates that the stretching produced slack in the tendons, lessening the amount of muscle force that could be transferred into the shot. One caveat: The study had good scientific controls and balancing of treatments (test routines). This was, however, an exploratory study and raises as many questions as it answers. Also, although the study was done back in 2010, it is still cited as a primary work in recent reviews. A quick online search did not reveal any follow-ups on the study. For those interested, the study PDF is below. PassiveStretchGOLF.pdf  
    • I have trouble with vertigo on occasion, but have gotten nutritional and biofeedback tips to keep it at bay. Dehydration can help trigger v-like symptoms so one recommendation, along with maintaining overall hydration, is to start with 8 oz. of water early in the morning. A meta-analysis on Golf As Physical Activity indicated that golf is rated as a moderately intensive physical activity. This scientific literature review came from the University of Edinburgh. The physical activity level ties into hydration. A former university colleague was a marathon runner who had published a couple of articles on endurance training. He likewise said that golf was a moderate physical activity especially when the round stretched past  the two-hour mark. For hydration he recommended switching from water to electrolyte drink on the back nine (past two hour point of exercise) to prevent cramping. At the two-hour point of moderate activity, water starts flushing electrolytes out of the body, which can lead to fatigue and cramping. (I have had trouble with leg cramps in the past during exertion.) During a round, I start out with water on the front nine and switch to sports drink on the back nine. If the day is unusually hot, I may drink 8 oz. of Pedialite concentrate before going to the course. Maintaining overall hydration plus on-course boosters keeps me going.
    • Personally I’d try booking direct first - either via the Vidanta golf reservations number/email or through the resort concierge - especially for Christmas/New Year. Vidanta’s main courses (Greg Norman and Nicklaus designs) are popular and can book out fast this time of year, so direct often gives you the best shot at your preferred tee times.
