I do really like Carbon Handle alway have, but I dont use them any more. I got so many bruises from that damn thing smacking my legs. Also I have noticed that when your spinning sometimes really strange things happen, on HS 7s every once in a while I will snatch the handle with one finger or grab the side of the handle, its WAY easier to recover and save the trick with a traditional style handle. The fact that the handle will flex a bit if say you grab it with one finger all the way is great, it wont get ripped out of your hand.
Just my $.02
