My two relevant experiences with this:
1 – My last tournament was at EGO Nashville. I was sitting on the bleachers and stretching a little, when a dude who was sitting on the floor behind the bleachers asked me, “Hey man, do you know Brandon Mccaghren?” (He saw my 10P shirt and drew deduced some connections). This started a short conversation, as this guy had crossed paths with B-Mac on occasion (all positive by the way) at seminars and such. Then he asked me what division I was competing in. When I told him, he patted me on the shoulder and said, “Whew…glad I don’t have to worry about rubber guard then since we’re in different divisions”. It was cool…just the knowledge that he might have to compete against 10P made him worry. Good stuff.
2 – The weekend after M3 I went to a local Gracie school for a Saturday morning open mat because some of our guys had fights that weekend and we weren’t going to be rolling that Saturday at our 10P gym.. I wore my gi (for like the 4th or 5th time ever), and we all rolled for a few hours. I electric chaired the shit out of several people…not to be a dick…but because they were all easy to catch it on. No one acted shitty about it, and nearly everyone said things like, “Yea man, gotta watch out for that Eddie Bravo shit…just ask Royler”. I even caught a go-go-plata, and dude was super cool. Don’t get me wrong, I got caught with some shit too (mostly gi chokes), but the point is everyone was really cool. The instructor, who I actually started jj with under a 30 day trial before I went to the 10P school I’m at now was also very positive. These guys could have easily been dickish about the whole thing, but they all acted cool and recognized 10P for what it is (in my opinion anyway). Good experience.
