PL O/8 low-stakes STT questions

[2Fast]

I'm normally a NL MTT player but lately I've been playing a lot of PL O/8 STTs bc they are a lot of fun and so far I've been doing pretty well. Am sure this is mostly variance but I really enjoy them and it's a great change of pace from NL all the time.

Anyway, I just have a couple questions/observations about the PL version of the game at the lower stakes.

Genreally I limp a lot (as do others) in the early stages and wait to see the flop, and will call with a lot of hands if it's cheap and I'm in mid-late position (or there are a couple limpers in front of me). I don't raise alot early pre-flop unless ther are only a few limpers and I've got stuff like JJA2 (or KK and AA with any other low cards) since from what I've seen generally at the low $1-5 stakes I play early raises don't get a lot of respect anyway and just build a big pot that will be hard to play.

I have been playing pretty tight post-flop early on too (dumping hands that miss or don't connect with enough outs) but when it gets toward the bubble I generally become much more aggressive and raise a bit more pre-flop even with stuff like JJA6, QQ23, KKAQ etc.

Am just wondering what people think of this type of play at the lower levels and also when people generally open up their game. Thx.

Note: I read the article by Frank Jerome about opening hands and found it very interesting and that's sort of what I've been playing (except I was also playing middle pairs with mid suited connectors, which is a no-no apparently)
