This came out today in that mine of golfing lore, Forbes: http://www.forbes.com/sites/stevensalzberg/2013/04/29/the-physics-of-golf-whats-the-ideal-loft-to-hit-the-ball-farthest/ Very short explanation of how it is that drivers are not lofted at 45 degrees. Link to a scientific article with the formulas. [Excuse me, "the formulae." :)]

That article is very ... odd. I already knew if was spin, but I guess I never really thought about the first guy to come up with that. Still, it's a strange read. I do like the equations and graphs in the linked PDF. That was neat.

In my bag:

Driver: Titleist TSi3 | 15º 3-Wood: Ping G410 | 17º 2-Hybrid: Ping G410 | 19º 3-Iron: TaylorMade GAPR Lo |4-PW Irons: Nike VR Pro Combo | 54º SW, 60º LW: Titleist Vokey SM8 | Putter: Odyssey Toulon Las Vegas H7

It was satisfying to read.
However, how good an explanation is it today? I mean, both balls and drivers are way different from those available in 1983. Dimple design differs. Different drivers of the same loft will produce different spin rates. The COR of a modern club is different from a wood or steel driver of 1983. Heck, even tees are available in more variety today, and the height of a tee has a big effect on distance.
And spin is not necessarily your friend if you're out for distance. The forward force on the ball is dissipated to the extent that loft creates spin -- and part of that pertains to materials and driver head design as well as golf ball design.. The right rate of spin will maximize distance but if the spin rate is too high or low the ball travels a shorter distance. Sure, the physics is the same as in 1983, but the equipment may give different optimums today when spin rates and lofts and distance are graphed.. Is this correct?
A fact that fascinates me is how pro gambler / golfers will grease the faces of their clubs with vaseline to increase distance. They want to reduce spin to get a more boring flight, with less diversion of force into spin.

    • You all are right, its not that big of an issue, I'll leave it alone, especially after looking at that picture of Tigers beat up putter. But I also noticed the small circle worn on the sweet-spot where he hits it every time, I definitely don't have one of those. Thanks for the replies   
    • Committing to one brand of ball this year - Snell MTB Prime X, the 5 doz. pack. Like how they perform for me. At $18/doz., can live with cover scuffing. Iron regripping with GolfPrice MCC+4 Teams std. in red/navy. May be retiring Odyssey Dual Force after 30 yrs. Seems like I can't get it to the hole anymore. Kind of light and has lots of toe hang. My reg. group's hounding finally wore me down.    From Callaway preowned - trying out the Odyssey Tri-Hot 5K in double wide (less toe hang) and triple wide (face balanced). Both also noticeably heavier...we shall see.  
    • WOW, it looks like he has been hitting stones with that putter to put all of those nicks into it.  I can't see how a ball would cause many those dings.
    • I'm fighting a knee as well as a foot so I "Feel your pain".  Luckily for me the PT is helping at this time and I am hoping knee surgery is not imminent.  Best of luck to you.
    • I would guess putting grooves in it might make it non-conforming. I am not sure how stringent the USGA is on restoring golf clubs.
