As a not young golfer and a constant hunger to consider change, I keep experimenting. I'm set on my clubs, so I've toyed with balls. There is no shortage of advertising for softer balls, I've tried a few (mia culpa - not all are Titleist). Across all clubs, none can match a Pro-V1 for distance and control. It is consistent that I can subtract a few yards. Whatever the benefit is for a soft feel or "designed for slower swing speeds", the only advantage may be price. I consistently find myself in a better position to score better with the V's.
My GolfSpy has confirmed this with ball testing. They're not a marketing arm for Titleist, but find that softness is a trade-off for performance. I'd have to agree. The day may be coming when I'm playing the front tees on a limited income so I may decide to go with TruFeel, but for now will stock the 4-4-3 deal during our Still Winter season in WI.
