My impression is that given current conditions in online 6max SSNL (at least at pokerstars and full tilt) never limping preflop is probably optimal. People assume this means that never limping preflop under any circumstances is optimal. But there are plenty of full-ring games, especially full-ring live games, where limping a lot is definitely hugely profitable. Playing live 1/2 or 2/5 NL at Foxwoods or the Borgata, for example, it's definitely +EV at many tables to play around 70/15. The 15 is your "normal" 15, but you just limp almost everything else. I know because I've done it. So though I don't have the book yet, seems to make sense to approach it with an open mind.
