so i got two 6.0 85 and I want to match them. I am thinking of buying a viper board (not too happy about spending $30 on a board with a bar... if you got alternatives please suggest) and a postal scale and get the two 6.0 to weight the same and have the same balance point. My question is, if the two racquets weight the same and have the same balance point, then will they feel the same when swinging? ie the swingweight, manuverability, stuff like that. also, i have heard that lead tape changes the feel of the racquet. well, if two racquets weight the same and have the same balance point, but one has some lead on it to achieve those spec, will they feel different just because one has lead on it? if i do decide to match them, i will string them and grip them with the same strings and grips before beginning any matching work. one more thing, if all else fails, i was thinking of getting a pair of k factor 90. i know wilson doesn't have a good reputation for quality control, but buying both racquets at the same time from TW will probably mean I get two with very similar specs right? anyone has experience in something like that? I wish they sold k factor 90 in matched pairs like the ps tour 90.
