At low levels, I limp all pairs up to 88. 99+ are raised. I limp Arag sooted but only if there are a couple limpers in front of me (Need to be some people in the pot to pay off the flush). I have stopped limping this in EP for that very reason. I dump them to a raise unless I have to call a relatively small bet in proportion to the pot. You get your flush about 1 in 3.5 times, so you don't want to be putting calling a $1 raise into a 1.50 pot to chase a flush IMO unless you are positive everyone will come in behind you and the pot will not be reraised...and for heaven's sake, if you flop 2 of your suit, bet your draw to build the pot!!!
