I am just getting back to tennis after a 15 year gap. My old Prince Graphite 2 MP is too heavy at over 12oz for my achy shoulder and I was advised by my proshop to try the Volkl Organix V1 MP. It felt very easy and the power from the baseline was controllable, nice pop etc. H:?owever I also see the PB V1 on sale for $99. Is there a significant difference? I have also tried several other frames, Babys, Heads etc but the Volk felt the best.
