how to play suited connectors in a loose LLHL

I'd like to hear your opinions on what's the best way to play siutyed conectors in a typically lose LLHL game. My curent strategy is the "pump or dump" strategy as ilustraetd in Phil Hellmuth's new book. I tend to limp in with them in late positions agasinst many calers. If i dun get a perfect flop or a perfect draw, i tend to dump them at the flop. 1) say i'm on the buttron, is it correct for me to call a raise cold (from a relatively tight player who only raises with premium hands) if 5 ppl have already called the raise before me? 2)is it ever a good strategy to raise with these hands prelfop in a loose
LLHL ? i feel like these games is pretty much "no fold'em hold'em" so any fancy play preflop seem to be worthless.

with the way I play ambiguously suited conectors so far, the money return hasn't been worth the investment. Any help would be greatly appreciaetd
