hi tw (or anyone that knows..)
1) do the yonex sensor butt caps you sell work on older yonex racquets not on the compatibility list and give accurate results using the sensor?
2) same question with the wilson sensor butt caps? (i.e. is it possible to use the sony sensor with an older wilson blade 93 and get accurate results?)
the sensor makes you choose the racquet from the software list and im thinking as long as the head size and brand are the same it should give decent results...
ive heard mixed answers...
thank you and happy holiday!
