Skip is one of the best. You are in good hands and it is showing. Great improvements bro. I hope they do drug test that show. Not only would it even the playing field for you but it is a classic show and should be a tested one. You should try to do some classic poses as well to show off your small jointed frame. Look for some pics of Steve Reeves, Clancy Ross or Ed Corney. Choose poses that show case an elegant/classical build. Good luck and I have a feeling you will do well.
Ps. DON'T shave the hair. You are right, half those guys are bald or have plugs. Just get it trimmed, especially on the sides so shoulder width is shown to it's best advantage. You could also gel it down as Arnold did at the 80 Olympia.
