UB NL cash games

[MediaPA]

I haven't played for a while, but it seemed to me like games have tightened up a fair amount (not many big hands, calling of bets/raises, etc). Just didn't seem like people were getting stacked or doubling through often as often as I remember. Part of it probably had to do w/ playing 6 handed mostly, but overall it seemed much more conservative than in the past. The games I'm referring to are primarily 400 and 1000.

Am I off, or has it become slightly more rockish?
