Here is a question for any of the stringers for the pros or coaches: Do the touring pros have racquets of varying swingweights in their bags to suit the surface or weather conditions? I ask because if I play with my racquet, which has lead tape under the bumper, on a medium paced outdoor hardcourt, it suits me great. If I use that same racquet on a faster court (ie. indoor) I tend to hit late and or long. I noticed that if I have one racquet in my bag with less or no lead tape on the head, I play better on the faster surface so that's why I was wondering if the pros have differing swingweights in their bags.
