We have a quote from The Dark Knight that we use fairly frequently among ourselves, "If you're good at something, never do it for free." The dual angle is a great technique, but is it wild and revolutionary? Not really, just a lot more accurate. I haven't seen what's up with the tri-grip yet, but I'll bet it's really great. How much greater than other top of the line fitting techniques? Not sure. If it's a more standardized way to better fit people, great, there's shops out there that completely butcher fit and need to be taught correctly. Sometimes though, I think concept and principles trump technique, or are at the very least equal. Like listening to someone playing music, sometimes the perfectly timed music off the sheet doesn't quite get it done. Fitting to me is a pretty personal thing, everyone's hand is different, so if you aren't sensitive to every little thing about someone's hand, it's not going to be right. Can someone be fit well without the tri grip? Sure. Can they be fit better with it? Don't know, but I would like to think Bill isn't charging 200 bucks a pop for something that's basically a different angle on something a lot of us already do. Sometimes a technique is simply a different method of doing the exact same thing. My grandpa "invented" the Glade plug-ins, or at least grasped the concept of placing a pack of something scented on the dash of his car when it was hot outside. Somebody came along and adjusted and marketed the idea, and they're a genius. Not sure whether this is the same deal or not, but we're confident enough in our fitting that we aren't going to drop the 200 bucks just to find out it's basically the same thing we're already doing. I'd consider myself a fitting expert too, I've put a lot of time and effort into research about the human hand too, but nobody's going to pay me 200 bucks because my name isn't Bill Hall.
