BTW: I'm talking about NLHE. In Limit I mix it up and only open limp at loose tables where I start adding Axs and pairs under 77.

Part of the problem I have is people do notice that I play tight and raising from EP will get less dead money into the pot and once they start putting in chips, they're going to keep putting in money until they see a flop or have their stack threatened.

My biggest concern is getting isolated by an aggro player, however a single raise isn't going to get the job done as I usually can count on 1-2 other loose players fustrating his efforts to isolate and bluff me.

By limping from early position I get the chance to play good hands against bad players, but get to see what stacks/players are in the pot before I commit chips to the pot.
