An intermediate doubles player's first two hours with the new 4U Astrox 88S Pro (BG66 Ultimax at 27 lbs), compared with six months on the Astrox 77 Pro: slightly more head-heavy in feel, a little slower, and softer in the shaft than feared.
“Stiffness - the new 88S Pro bends more than the 77 Pro, feels somewhat softer. Initially I was worried that the racket could be as stiff as the previous 88D Pro (the gold colour) or 100zz”
