limping against fish?

[hansdebelge]

i play in a 20$ buy in home game with some friends. usually there are about 8 or 9 people who play and 1st/2nd/3rd get money. i am definitely the best one there, i got them into poker and taught them the basic strategies.

since it is a friendly game, there is not a lot of very aggressive moves and its always fun. lots of times, everyone will limp in all the way around to me. i play basic conservative style against them and it always works, especially against the one loose cannon at the game.

my question is: if everyone limps in to me, as often happens, and it is 25 cents or what ever to me, is it smart to just limp and see what happens with average hands like K-5 of Q-9 or something. in more serious games i would never play those, but with these guys i can be 85% sure there wont be raises behind me. everyone likes to see a cheap flop then get out if they miss. should i stay tight or should i start seeing cheap flops with big potential pots. whats the EV on that?
