I have a T-Bar at my resort that accesses some kinda backcountry stuff. I will agree that T-bars in general are made for skiers, they simply are never comfortable for snowboarders. The way ours is set up though you can ride it with both feet strapped in, there is a cattrack that leads to it, then you can skootch to the end of the line, and then get some skootch speed to where the T-bar comes down. Having both feet strapped in is a big plus, because I know what you mean about the track getting squirrely and it sends your board all over the place. I don't personally like riding it all the time, but it's fun every once in a while when the powder is good.
