I have to disagree. I'm logge a small sample of around 7k hands at 2NL and it's fairly loose still imo. In my experience at everyone FR table their will be 1 or 2 multitabling nits. I'm actually pretty certain the "weed smoking" guy you are talking about, name chrisc (something like that).

Anyways, you are 100% correct on the reasoning for big pots + high VPIP. I consistently see guys with 65/4, 70/8 stats at this level, so yes they limp like fucking crazy from any position at the table.

But them not stacking off with TPNK, and draws? Maybe a few don't, but the majority does so with a high frequency. You can ever find a few donks still that will stack off with middle pair, or on a 1 card left to come gutshot, or even better yet when they shove with total air.
