If you are planning on MX or similar with it, CT is a good choice. You will get a very tractable power from whatever he sends you, will have good torque numbers HP is not real high on his priority list similar to LRD/LED if you get to talking to them. Allen will build you a engine that is not flashy but puts power to the ground and doesn't wear you out, if that's not what you are after I would continue shopping. One should also keep in mind that when they look at a CT Pro X it probably isn't altered much considering he was the designer of it, my LRD Pro X looks very plain also for the record but runs nothing like a unported cylinder.
