fuck bro, you have great size... you should shred it up a bit and you will be an absolute fucking monster... i can't see any reason to try to bulk anymore than you already are... to each his own and if that's what your after then go for it, but at your height, how much more size do you really want?? you have an excellent base right now... if you cut a bit i think you would be really happy with the results... you don't have to drop a bunch of weight, just shred it up a bit...
