If your planning on the street as a testing ground be prepared to get some nasty beatings, without the assistance of a referee!.
I know some people think its hardcore to say they don't want to grade, but their usually the one's talking about competing so your a little confusing. Also when you do join, if you decide never to grade one day when your refering to your fellow beginners as "Sensei" you'll rue your decision.
Muay Thai is an excellent fighting system, its fast and furious, great for a stand up street fight. But over 90% of street fights go to the ground, and thats where you want some grappling too.
Really I think you should reaccess your goals and what you want out of a particular M.A.
