Def make the best out of the two motors but use your bottom end. I cant even tell you how many times I have heard a motor from SGP has not held up...It seems as though there are a lot of bearing issues with their motor builds. Good luck man. Def stick with the motor you know has a good bottom end. I do not trust SGP at all. Hope this helps...
