Hello All,
I just got around to replacing the plastic pillow balls in the front of my TT02 with the low friction metal balls. I have to say I was pretty surprised by the amount of scoring on the plastic balls after 10-12 full packs (3ish hours of use). I have yet to drive it, and I am guessing I will not feel any difference, but the metal balls are a heck of a lot smoother then the plastic ones when you spin them by hand in the arms. You can also tighten them a but more before you start to feel resistance. Time will tell how the do in the long run but right off the bat I am thinking they are worth the $5 and 10 minutes to install.

Cheers,
Jim
