I currently play a Cleveland Comp 10.5 degree with a speeder 569 stiff shaft. This has been a great fit for me, and plan to keep it in my bag for another season. I currently have 2 additional heads to play with. One is a R580xd tp head in 10.5 degrees, the other is a R7 460 retail head in 10.5 degrees also. I was considering an Avix 5564L which was suggested in the fitting thread. Do the TM heads have similar launch angles as compared to the Cleveland? Would I be better off with another speeder 569 which I have or going with the avix?

IMO the Axiv every time, it is new technology compared to old. You may want to check out the Axiv V if your bad shot is a pull hook.
