i had been playing with a shortened racquet by 1cm. 348,5gram, 31.5 balance 326 SW. I decidedto test out again a normal 68.5. All the lengths are strung lengths. Assuming you extend the above by 1 cm the new balance point would move to roughly 31.9cm. However such a move would materially change the mgr/I since the latter is dependent on the balance point in cm. So initially decided to maintsin the same 31.5 balance so as to keep mgr/I unchanged. I could not hit a normal ball! Felt too HL. So i am thinking for a different racquet length there is a different optimum mgr/I. A factor that i think supports this is that 31.5cm of balance for a 67.5cm racquet in points in almost 1 point different (more HH) than for a 68.5cm racquet. So i modded the racquet to maintain the same balance in points while obviously increasing the mgr/l. I will try this on Friday, but any input in advance would be greatly appreciated.
