So I've been training boxing on-and-off for a while and my trainer informed of of this Anniversary thing they have at our gym where they hold a few amateur fights and he asks me whether or not I'm interested, to which of course I answer yes. I'm supposed to start full sparring now (yes, until now I've only hit bags, balls and mitts). I do have a general knowledge of how to strike (I watch a hellova lot of MMA, and boxing occassionally). I'm pretty sure I have a lot of power for my weight class, but my endurance is a bit shady (I get tired after 3 3minute rounds of mitts). My footwork and evasion are decent but not special. My technique is also decent, but then again, probably nothing special. I'm 5'6.5 at 130 pounds. So my question is, what style of boxing should someone like me use, so that I could base my fighting on that and further improve it as I get used to sparring. Should I just use my power and brawl? counterpunch? Stay on the outside? Is going for that knockout punch immediately a good idea with the headgear and all? btw, I'm using boxing as a base to hopefully move to MMA.
