I've been reading Harrington on Holdem Volume 1 and been trying to apply it to my small stakes 25NL cash game.

Harrington suggests as a generic play to start raising 3-5 times the BB with pairs as low as 66 in late mid position (88 in early mid position!). With regards to small stakes holdem NL cash games, particularly NL 25$, is this insane or what?
