While it hasn't been mentioned, the Thunder Tiger .46 Pro is only about $25.00 more than the Magnum and runs like an OS .46 AX. There is the Evolution .46 too. I have the Evolution .61 and its probably the strongest running .61 I've had off a tuned pipe. I've seen several of the Evolution .46's and they seem to be strong, very good runners and dependable - no problems out of them.
