Hmmm. First, for Bruce, I come off the ball with more speed than I used to. I don't know if this makes sense wording wise, but in order to create the right finish to the turn, I feel like I need to create the right start to the turn, which to me starts right off the second wake. By establishing the arc of the ski off the second wake and going out on the inside edge, I find the ski creates a natural finish rather than me having to "force the finish". Second, yes, I have run 38 this way and while I have been making 38 for years on an inconsistent basis, my consistency at that pass has increased dramatically using this technique. I do agree with you that it is a big increase in control. As I noted in the first post, I am trading "consistent speed" for what used to be an effort to generate maximum speed. Rather than speed up, slow down, speed up, slow down -- I feel like the speed is constant with only slight variations as I hook up, accelerate to the center, then release and glide fast up to the ball.
ShaneH -- conventional wisdom would suggest that the early edge change (not releasing the handle, as noted by 6balls) would limit width. I always believed this to be true. In the last year in practice I have found this to be false.
Width is a combination of moving out and moving up on the boat. I release the edge when I feel the handle starting to load, which occurs right after the centerline of the pull as the handle is now moving forward and out while the ski and skier are moving straight out (in theory). This reduces the load on the ski and allows it to ride higher and faster as it goes out and up. In practice, what I have found is that this to be false. I am, in fact, both wider and earlier than I was when I pulled longer.
MS -- yep, if I think about keeping both my vision and my ski moving at all times (never get "locked in" to a position), the whole thing is awesome. Even in the lean I try to ease into it, and ease out of it rather than feeling like I am just holding the lean.
Davemac -- I used to do what Regina did and just pull on the line longer to get around a ball after a mistake and try to get one more that way. Essentially the old "beat the boat" technique. It will get you one more, or maybe a half. Oddly, at least through 38 off, I have found that with this technique if I make a mistake let's say at 3 and am late across the wakes to 4, I will be EARLIER to 4 if after the second wake I actually over-emphasize my edge change and still swing the ski out early. IT is a really weird mindset, but like 6balls said, I just keep telling myself to "get off it, get off it" when I am late across the wakes and then similar to what I said before, I am actually both wider and earlier to the ball than I was in the old days when I would essentially pull all the way to the ball. Instead of being super fast and out of control at the ball, I am in my normal position, but probably just a little further downcourse than usual. I am better controlling my speed.
As for Regina's epic wipeout, I can't say whether or not this technique will work at lines shorter than 39. I have run 39 (once) using this technique and when I did it right it felt oddly easy (ZO, private lake, surveyed permanent course). I know it works well through 38 for sure.
