Hi Crocodile
I've just tested a few Volkl frames looking for a replacement for my POGs which I've used for years. The week I hit 30 my elbow gave up on me and asked for something flexier and more comfortable. I settled on a Tour 10 MP weighted at 12g over stock strung weight.
In getting there, I tried the Catapult 10. It is a strange racquet because it is a bit contradictory in its nature, but I couldn't help but like it even if it wasn't quite for me, yet. Like many others on this forum who have tried it, I found it too light at this stage in my game, and too unpredictable because of the Catapult technology, unless you strung it at 60lbs+. That said, strangely, I found the Cat 10 to still be a racquet that requires a technically good, full stroke, so in that way, it is different to typical 'tweener racquets, and probably different to the higher powered Cats . Of course, as age catches us up, the benefit of the Catapult will show in helping generate power (at a lower tension) as we gradually start to ease up on how hard we hit.
IMO though to get the most of the frame, the shoulder still needs to do the work in terms of rotation etc so like I said above, it may be that the more powerful Catapult racquets will make less work for your shoulder - I'm guessing because I haven't used one. The Tour 10 VE is not supposed to be that different to the regular Tour 10, just a bit more pop.
It's all a question of where you are with your game. I said to myself when I tried the Cat 10 that it would be my perfect racquet if it didn't have the Catapult technology and was about 25g heavier - hey presto, the Tour 10 MP. If you are struggling with the Tour 10 because of the work your shoulder needs to do, then I'm not the Cat 10 is the racquet for you and to perhaps try the higher-powered Catapults will help more than the Cat 10. If it was your elbo causing problems, I'd recommend the Cat 10 if the Tour 10 is proving troublesome.
For what it is worth, a family friend who was a 5.0 went from a POG to a Head iS6 at the age 40 and sings its praises - he is good enough to know how much work he needs to do with that racquet with his arm/shoulder before letting the racquet do the rest for him.
Good luck
