GGO, I certainly see the point you are trying to make, and agree that the scoring system should be adjusted. That said, I respectfully disagree with part of your premise.
You state: "I, for one, play in tour master conditions with K15 clubs or Raptures + Calloway balls, scoring decently, but definitely NOT well enough to warrant my crazy 61.xx average." I think you are mistaken and are actually a better player than you give yourself credit for.
I looked at your score history, and you are consistently 3-6 under on 9's and 5-10 under on 18's, even on the tougher courses. To me, this is consistent with someone who has the game down pat at their current level.
I also looked at your stats (and I understand that they are skewed because you had a previous ID). However, you have a birdie/bogey ration of 8/1. You have 87% driving accuracy and 85% GIR. Your sand and scrambling %'s are 62% and 74% and you make 52% of your 1st putts. These are outstanding statistics at any level (I wish mine were that good).
I understand your point that the legend tees might put these statistics at risk and lower your scores, but I'm pretty sure that someone with your skill level would adjust quickly enough, even given your stated product limitation.
When I made legend a few months ago, I was hitting the ridiculously wild 278 yard SuperTri. My scores were going over par far too often, mostly because I was missing too many fairways. I switched to the R9 275 yard driver, which has a considerably lower swing meter than the SuperTri, although, obviously, not as slow as your K15. My scores started coming down dramatically. Of course, WGT came out with the R9 280 yard driver shortly thereafter, but that's another story (WGT always comes out with a better product the day after I buy new equipment.....I'm like a contrary indicator).
In a nutshell, I don't think you should "dread" making it to legend status. Perhaps you might want to try out that 275 yard club. Sure, with your "slower reflexes" you are going to miss the meter more often than now, but even if you are still in the fairway 70% of the time, the rest of your skill set suggests you are going to score just fine once you learn the longer approaches.
Just for fun, though, I'm going to go rent your equipment set and play a few rounds from legend tees. If I can't break par due to the distance shortfall, then I'll suggest you give that 275 yard driver a try. If that doesn't work for you, then I'll agree that a slightly longer driver with slow meter speed is needed....but only for legends.
