I have aquired a few old school racquets in the past few months and would like to string a few of them up. I have been using a hybrid setup in my newer frames (good multi or syn/poly) and am curious is this would work well in frames such as: Puma Becker Winner Rossignol F250 Max 200G, 300i even the 6.0 85 or is the flex, power level too low for a poly string? Anybody try poly's/hybrids in older frames? I love the flex, feel of the older frames and the touch that goes along with it unlike the newer frames where is is difficult to play any finesse shots. Thanks in advance.
