Limping in from SB as big stack?

[GoldenHorde]

Sitting with say 20X the BB or more and 2-4 callers I will usually limp in from the SB with subpar hands like say q-9s or 10-8s stuff like that hoping to flop trips or two pair to take out a small stack or maybe a nice draw to put a shorter stack to the test. Those are cards normally I would just throw away if I didn't have a ton of chips to back me up.

Is that something i'm going to be getting good value for or am I just pissing away my chips?
