Well, judo will help your wrestling, Muay Thai won't. That's for sure. But I won't tell you what to do. Maybe you really like Muay Thai and want to get better at it. Maybe you want to get into MMA. I don't know. But judo will help make you a better wrestler. You'll have some "unorthodox" throws that a lot of wrestlers aren't prepared for.
I've only done MT for a few weeks now, and I do have fun with it, but now would be the time to make the chanege. I really have been working to be a better, and more succesfull wrestler, and I like MT and MMA, but not enough to pursue a career or competition. Not now atleast. Now I just want to focus on wrestling, and anything that would help give me an edge. Judo sounds fun, looks cool, and if you say it'll step up my game, then I think I'll make the switch. Thanks for the insight.
