The argument for bifurcation is a specious one, IMHO. What exactly is solved by that, other than making the PGA more interesting to watch? I'm baffled by people who don't think it is a problem that distance increases are obsoleting courses and have completely changed the game. I think it has become too convenient of an argument to claim that all the distance benefits from new equipment have gone to longer hitters so that shorter hitters who also benefitted can continue to fool themselves into thinking they've always been hitting 8i into that 400 yard finishing hole at their home course.
Now I'm sure some of them either didn't play 20 years ago or that 20 years has taken them from their prime to shall we say sub-prime due to the simple ravages of time or poor health choices catching up with them or whatever. But if someone went from say 40 years old to 60, or 50 to 70, and were still hitting it the same distance, they might want to think about whether that's because they are such a perfect physical specimen or because nature's been getting some help.
Now personally I'm 38, so 20 years ago I was 18. I swing much less aggressively now than I did then, but I'm longer than I was then. I'm certainly not in better shape, as though I'm in pretty good shape for 38, I was definitely in better shape at 18. And since I've never had a lesson, it seems unlikely that my self-taught golf swing has magically improved (unfortunately, the reverse is more likely true) So I really can't claim that me hitting futher today has anything to do with anything other than the equipment!
Back when I was 18, a 7000 yard course seemed really damn long. A 450 yard par 4 was a brute, something I'd think I'll probably need a 5i approach if hit a good drive, only rarely less if I pure it or have help from the wind or firm ground. Nowadays if I'm hitting a 5i to a 450 yarder, I missed it badly or I've got the elements again me.
Brent bringing up Brad Swanson is sort of apropos... I recall playing with Brad a few years ago, on a course that was something like 7150 yards long. We had our difficulties (due to a 25 mph wind and some missed shots from each of us) but we were both hitting it about the same distance and both agreed after the round that the course seemed kind of short. This was a fairly new course, from the tips. We got to discussing how things have changed and he echoed my comments above about how 7000 yard courses and 450 yard par 4s used be long, but aren't anymore.
I just don't buy the argument that we should bifurcate because the short hitters are enjoying being able to play the 6700 yard tees, so for us longer hitters we should either play the shorter ball on our own or everyone should have to pay more so courses can be modified or designed with 7500 yard tees so we don't wear out our wedges. If the next ten years brought more "improvements" such that short knockers were able to play at 7400 yards, then they'd whine at the thought of having to play at 6700. I think probably a lot of older guys have had their aging hidden by technology and still think of themselves as a player capable of playing a 6700 yard course because they could when they were my age. If I'm still able to handle the 7510 yard course (at sea level) I played last year when I'm 58, I'll KNOW the technology battle has been lost, and after I get home from that round, I'll flip on the TV and watch the pros hit their wedge approaches on whatever 8400 yard TPC course they'll be playing that week.
For the advocates of bifurcation, how would it work? Is it just a ball for tour? What about for college players who are hitting it at least as far as the top pros now, or the outlier amateurs that Rich brings up? Do we try to work in an adjustment to the handicap system so short knockers who use the hot balls can play against guys using the short ball? I do have to admit I'd like to see the Masters create a shorter tournament ball and make everyone play it, just to see what happens. But I suspect they are a bit too traditional for that. But they are the one place that could get away with it and still have all the big names show up.
