I'm a super-low roller and I doubt I attract much attention. (That's why I was playing the $3 table; I actually can't afford to play-all at a $5 6D table.)
Also I don't think that game is too impressive. The pen is decent but nothing spectacular and I don't know how it compares to Mystic because I didn't have the time to make it there. The rules are nothing special (H17, no surrender). I think at least Mystic has surrender. Further, that $3 table is usually packed.
Finally, a whole bunch of people played that table that night. I wasn't alone for long, and after several hours during which I never bet more than $50, I managed to lose a little bit for the session. I wasn't even the highest bettor at the $3 table most of the time. So I doubt TI cares too much about people like me.
EDIT: I should add that, if I remember right, the table max there was $100 instead of the usual $199 on the rest of the main floor. I could be wrong about this as my memory is hazy. Anyway, I can't imagine how any serious counter could make much at that table. I would also think that a casino benefits from the super-low stakes because the ploppies at a $3 table should play even worse than those at a $5 or $10 table, but there were some truly atrocious ploppies all around there.
I will say this about TI, even though it's only based on the impression I got: Their pit is NOT dumb.
If I have said too much, please instruct me to remove details.
