I was using the Hammerhead designs rocket launch on my last bike and it was a huge disappointment. It was harder to install and the fit wasn't as good. There was two times when it wouldn't disengage and I had to run my motos with the forks compressed. The Pro Circuit launch control device has been a sigh of relief. The parts fit seemlessly together and it is very easy to install. There is even an instuctional video on how to install it on YouTube if you're unsure about anything. I rip my holeshots with complete confidence that this thing will do its job. I would highly recommend this product to anyone that is in the market for a holeshot device.
