Not a fan of the name change, the existing system was perfect, the problem is that Track just wasn't good with developing balls according to their own system. The pieces were quite good, but I think this has more to do with them not being able to make a quality ball in their high end 900 range. For me all of the balls under 900 were fantastic, but the 900 series was so hit and miss.

Oh well, my favorite balls of that generation will always be the 920T, 505T, and 505C.
