Thanks bro! I'm looking into the Titleist options because I've got a connection and may be able to get a new set for cheapy cheap.
I love my Mizunos but I could honestly use a little more forgiveness...
I'd download and give it a shot, but then I realized it was iPhone only. I do have a couple questions about the app though if you can answer them, and if you can't they may be things for you to consider.
Is the app using the gyro/accelerometer to measure "true down" from the perspective of the phone and then analyzing slopes it sees compared to that?
Do you take into account the height of the phone from the surface of the green? If you don't, you'll run into accuracy issues if one person who uses it is 6'5" and the next is 4'10".
Does this work on all grass types, or only the more reflective and shiny grasses?
Does it take into account the grain of the grass for varieties like Bermuda?
What kind of putt speed does the app assume for your calculated break? Is it supposed to be dying at the hole, rolling 6" past, or rolling 2' past the hole?
How are you handling the digital stimpmeter? Is it something where you input the stimp of the green based on a measurement with a regular stimpmeter, or is it something where you can (for example) measure the slope of a green in a certain place and record a putt being stroked along that slope to get an idea of the rolling resistance of the green to calibrate the app? For the second idea, if you were to implement it, you could make velocity calculations without terrible difficulty (still dealing with image processing bullshit, but you're doing a lot of that already) since the size of the golf ball is a known quantity.
Do you use the plain camera image to measure the slopes, or are you doing something sneaky and using something like the camera's focusing feature to try and get an idea of the differences between the high and low points?
What is your monetization plan? Will the app be a 1 time purchase, or will it be "freemium" with basic functionality and ads/basic functionality and upgrades?
I've used the same Sun Mountain Three 5 bag for the last 7 years now and I can definitely recommend it. It's certainly been durable, since my only issue in that entire time is last summer the rubber carry handle started to disintegrate so I don't use it anymore (leaves black all over my hands if I do). I could get it fixed for free by sending it in to Sun Mountain, but it's not a big deal to me really.
It's light enough to carry with no problems, but big enough to fit whatever you need. I usually carry with it my rain jacket (inside the large pocket), an umbrella (on the side in the umbrella loops), about half a dozen golf balls, three or four gloves, a copy of the rules, some jerky or other snacks, athletic tape, tees and ball marks and pitch repair tools (in a little pouch), yardage books, sharpies, various medications I need to have with me, and whatever other miscellaneous junk I've collected along the way. I don't generally pack that light, but I always have what I need if I need or want it (and I'm young for now, so it'll only do me good to carry around a little more weight so long as its not attached to my belly).
Every time I get fitted I get fitted for the best combination of clubhead and shaft for me, and what I'm looking for is generally the tightest dispersion pattern without sacrificing a ton of distance (5-10 yards is ok if the dispersion is significantly better). It's just worked out nicely so far that every time I've been fitted the KBS Tour X-flex shafts have been the best performer for me.
Since that is the case I've kept the same set of shafts through 3 sets of irons now. Ordered them originally to install in my s55 irons, then installed them in some 716MB's that I was testing head to head with MP4's, and then I stuck them in the new set of MP4 heads that I ordered when I determined the MP4's worked better for me than the 716MB's. The two performed about the same as each other and so it really came down to personal preference and comfort.
That said, I would switch to a different shaft if I could find one that made an improvement on the launch monitor for me.
