I don't know if it is just me or what. This afternoon, I was playing a match with a friend. I found out my shots are off a lot, especially the putaway shots. I was making a lot of errors. I also notice that my racquet is lacking the power I need for the shot. The "pocketing" feel is also gone. Is this because of the temperature? Anyone else has observed the change of the feel of the racquet? Can someone suggest a string that is good for cold weather? It was about 60F this afternoon here in NY. I was using ps tour 90, MSV hex 1.18 for main @50lb and MSV co-polymo 1.18 for cross @52lb.
