is there something to this?

i am noticing the TAG-regs at FTR carry numbers like 15/7 and 17/9 for full ring games. i am not noticing anything like 20/10, or 22/11 often anymore. i wonder if thats because they play higher limits, and, therefore need to tighten up? or because the game has tightened up a smidge due to lack of american super-fishies at night?

i'm sorry, but anything below 17/9 is super boring...even with 6-8 tables open.

opinions as to why this is?
