I was quite surprised at the improvements from the 125S. With less than five minutes warmup, I went straight into a vigorous match. Every shot I played seemed to be an improvement, my length was better, my touch was incredible and forehand smashes were pinpoint. My only reservation was that it felt quite a bit heavier. Very impressed.
Only used it 3 or 4 times but took to it very easily coming from the older Nick Matthew evolution racket. Actually the same head shape just without the gap in the frame.
