Right straight left hook.
Reasons:
1.Right straight can be very powerful and is faster than hooks or uppercuts because it travels in a straight line. Also, if it lands on the chin it can daze or even K.O. the opponent.
2.Also a right straight cocks my body anti-clockwise giving me a perfect wind up to pivot back clockwise with good momentum for a left hook. (Kinda like that drum toy on Karate Kid 2). If the hook also lands on the chin it can rattle the brain and cause a K.O.
You can't beat a good 1,2 jab, straight coming from a great outside boxer, when its landed by someone such as W.Klitchsko, A.Ward or F.Mayweather its a thing of beauty.
