Yonex Ai 98 vs Head IG Rad Pro


Anyone played with both of these frames provide some feedback on similarities, differences? They Ai98 had glowing TW reviews, the Rad Pro, good reviews. My guess is that they might play pretty similar, muted feel, flexy, good control, however, perhaps the Ai98 may be less sluggish.

Fire away...thanks

Similarities, static weight, string pattern, stiffness.
Differences, Swingweight, balance, true headsize.
