I have a hitec 925 MG BB, and I WOULD NOT recomend it. The servo works OK in off-road, but when I tried it in my TC, with the higher workload, it busted. Basically, it would have alot of trouble finding the corect center. I sent it in, and they got me a new one, but I use a JR 4750 in my TC. Not super fast at .12, and not super torquey, 73 ox inches, but VERy smooth. Also, it is not very expensive. I hear that hitec make some kick butt digi servos though!
