Six specialist tools! Nuts! I'm a toolfondler who doesn't care about the money those tools cost, but I owned several Citroen SM, in which where was no way to adjust the camshaft drive tension on the Maserati V6 (they left it off when they cut down the really good 4.2 litre V8 -- I had several of its superb, long-lasting 4.7 litre big brother as well -- to fit the very short SM engine bay behind the front-drive gearbox/diff), and it ruined the pleasure in a really good fast tourer knowing that sooner or later that absence would destroy another engine.
And on the other page you link, Dan, I discover that the tension "recommendations" aren't even firm, that purchasers of the Gates Drive are unpaid beta testers discovering the correct range of tensions for various classes of riders, at their own expense, of course. I've been an unpaid beta tester for Apple since Steve & Steve signed my first Mac in the hot plastic. I've learned my lesson: I'm not taking on Gates -- it could be a lifetime job.
Actually, my main beef is that I suspect that the Gates belt, with all those drive ridges and all that outside surface, will be a good deal dirtier than my narrow Chainglider, which is important to me since I cycle in street clothes, often light-colored.
