You sir, have provided the most informative post I've seen in a long while. The video examples were great and a huge plus in example and understanding. I think you're right, my instructor is a state-wide pro and he's trained a really good fighter I know, so I feel I should accept his concept of a good boxing guard, as well as other things. If I feel I should change it to another guard/stance, I will check into it. I'll definitely check here first though.
Thanks Tom.
