I have a questions on what tension range you usually string under cold circumstances? i play on those concrete hard courts, they are pretty slow and the ball is not coming to you... I uses a youtek prestige Mp... where i usually string my tension around 57 to 60 , thats my regular set up in hot weather and on fast hard courts. But i have been struggling with the pop on the racket in cold conditions... I have 3 choices, Full set of alu power or Wilson NXT , or i go for a hybird. any suggestions ?
