I have noticed that my jab by itself is very powerful, nice pop to it. If I throw a left jab and then right cross my jab is weak. If I really focus on my jab it will be slow, to get it more powerful so the 1-2 is very choreographed then. I have also noticed, something I really like is after my right to throw te left jab while backing out, and it is f-ing strong. Its a pop, pop, pop and back out type manuever, awesome though. I pretty much step to the left side and back when I throw it, I am avoiding the counter and inflicting some damage. Problem is when a good fighter picks up on it though. So to sum it up my jab is good by itself and good after a right cross, but very poor when leading the 1-2. I have tried to focus on it by hitting my 1-2 constantly but it is not correcting the problem. Also dont have the problem when fighting southpaw.
