pro taper "twister" throttle tube

[murphy's law]

Has anyone used this throttle tube with the sealed bearing insert. I was thinking of buying an aluminum tube but was skeptical because of the stories I've heard about how they are prone to sticking more so than the stock plastic ones. If you go on pro tapers web site you can see a cut away of the assembly.

Got one on my kids yz 125. works great. Never sticks, he rode all last year without taking it apart still feels like new. I am going to get one for my bike because I am sick of taking it apart and cleaning it. You have to be careful the first time you ride, the throttle moves so easily you find your self gasing it when your not ready.
