latest update.........
I think I am all set with the Instinct. I really wanted to like the London because the specs seemed perfect and the paintjob is so nice, but I just play much better with the Instinct. It gives me better power and it's easier to swing. I don't know why, but the Instinct feels much lighter through the air than the London. They are both about the same static weight (11 oz) and are supposed to have the same swingweight (312), but the London is noticeably sluggish to me when I play them both side by side.
When I measured the 2 racquets on the machine, the London showed a sw of 324 and the Instinct showed 310, so either the Instict is rated too high or the London too low?
Either way, I found everything I need in the Instinct to play my game. Light weight without feeling flimsy. Power on tap with some control. Very accurate due to the 18x19 pattern. Nice surprising touch for a tweener. My dropshots are as good as they were with "players racquets" and my defensive game and 2HBH have improved quite a bit. Anyone looking for the same qualities in a "tweener" should not let the Instinct pass by without a demo. It is very much like an easier to use Radical MP. I really can't find anything wrong about it, except for the Head pallet shape, but I did a DIY number on the handle and now it feels fine to me. Hopefully I can stick with this racquet for a good while or at least until next year's new models come out
