The new Ultimum 100 racket from Yonex is out on the 1/10/00. Anyone has any idea of how it performs?

Oh, I mean the Muscle Power 100, sorry.

Yes I tried it today. I had a little comparison between a carbonex-21, Ti-10 (regular length), and the muscle power 100. It seems quite similar to the ti-8. Long but not slim shaft. I probably got the best smash from the muscle power, the cab-21 and ti-10 were roughly equal. It has less vibration than the ti-10. It also has some special grommets that support the four main strings at the bottom of the head. The muscle power is a very nice racket but I'll still stick with the cab-21 which has the best compromise of power, defensive and net qualities. I'm still unsure about the iso head shape as well..
