I have a Insanity and have had a Destroyer, the grooves are deeper for that very reason and Bowtech adressed that with the Insanity. To me the Insanity is all that the destroyer wasn't. It has a smooth draw and stores a load of energy. A much better grip and feel to me also. I have had several different bowtech models and I like the way they feel and perform. Not a bowtech fanboy but I shoot what I like and dont listen to pro-con debates. And I like they way they handle vets and servicemen too. You show me how many companys worldwide that place a bible quote on their shipping box right by their logo? My kind of company!! I don't think you'll go wrong if you choose the Insanity, just shoot one and make up your own mind.
