Hey bro, just cuz you think you can't be more than 230lbs and cut, dont let that get you down.
Look at Chris Jericho, Lance Storm, Chris Benoit, etc etc.....all under 230lbs; but all of them ARE EXCELLENT mat wrestlers.
Pro Wrestling is all about charisma. I've seen/know countless number of guys who are phuking huge and can brawl with the best of them, but when you put a mic in their hand, the want to crawl into the corner like a little girl.
Being "big" is awlays a plus. It'll get you farther then just being in decent shape. Having good mat skills, being able to get a crowd behind you (either loved or hated); having a catchy gimmick, and working the mic well get you farther than anything.
I have a few buddies who tag team in Japan. They weren't shit here in the states, except for a few WWE (WWF at the time) dark matches. They are both over 6'2" and 275lbs, are are monsters over in Japan. The people over there LOVE to HATE them and they get paid well. Besides, Japan has some of the best mat wrestlers in the world.
Best advice i can give you is to try to stay away from the "hardcore" wrestling if you plan to make it anywhere in the business. Very few of these guys can actually wrestle, and once you get labled as a "hardcore/Trash" wrestler, Top Indy and WWE wont want you. Besides, the toll you body will take isn't worth it.
I've got 11 buddies who are Pro wrestlers, and I've had the chance to go do that myself. It's not an easy road to travel if your trying to make it a career. 3 of my buddies all live together in a shitty 1 bedroom house outside Chicago. They travel all over the midwest, and still make jackshit for cash. Maybe enough to pay for food and gas money. But they love it, and i dont blame them. Fans cheering or booing for you can really get you hooked.
If you just in it for the weekend warrior type, and just something as a hobby, then by all means go out there and have fun. Get the fans into it, and they'll show you some love right back.
In any case, good luck bro. Stay healthy and focused.
