Auto shifter ideas what's the best

Well as a former B&M ratchet owner...It wasn't nearly as bad as I thought it was. If I had it to do over I would have bought a Pro ratchet, and kept it. I had a quicksilver and since I race so much, wanted a mechanical reverse lockout. A cheetah is what I have now....not something I will buy a 2nd time.
right opposite , I had a pro ratchet in my aprox.600 horse vega, never again. The cheeta is really strange to get used to , but about as good or better than anything I ran.
