I used to limp a whole lot. I have changed to occasionally. I will almost always limp into a 3 limper pot from the small blind. Pot odds
One of the great things about a big stack is the ability to limp in with a looser range of starting hands.
I do still use limping as a way to try to tone down a high flying table early in tourneys. This is a weird usage. Maniac on table, I'm sitting out unless I get dealt top 3 hands. I chat it up a bit to make sure everyone knows I'm discriminating. Meantime the maniac is raising, the action junkies are following, and it is insane. 2 orbits in, so many are gone, damaged, or have already given up, that I might limp in EP with cards I would raise in LP. Surprisingly this sometimes starts a limpfest, which has the effect of slowing down the action to something approaching 'normal'.
If it has no effect on the players, that I finally got involved and decided to just limp, then the table is not ready yet to calm down and start the grind. It seems to be working maybe 60% of the time tho.
Late in tourneys there are times to limp with drawing hands and a big stack.
Overall, I finally figured out that limping is self crippling.
As for a total 'No Limp' policy. That I think would be wrong headed. Limping is a poker tool that will perform specific jobs well, better than any other tool, but it is too often used like a screwdriver when a hammer is the right tool.
