Suited Connectors in LHE:

I'm lost with my mid suited connectors right now 56 - 89. In NLHE I would usually in late position like to come in for a raise with these if there was no action before me and stuff like that, but playing suited connectors in limit is beyond me, I really really hate limping, nor do I know when it's appropriate to do so as far as how many limpers you have in front etc. any general guidelines you can offer me on this because so far they are in the red pretty bad.

Non-nut flush draws in LHE:

Should I either not be drawing to these or adjusting my odds if non-nut? I feel like I'm being overflushed about ever 5 minutes because everyone will draw to everything and anything in limit so there are often times 2+ people drawing to the same flush, so what's the verdict on non-nut flush draws?

BB/100 in LHE:

So far im at 1.17BB/100 which is not nearly as pretty as the 22BB/100 that I was making at NL25, obviously NLHE and LHE are vastly different in terms of BB/100, but it still seems low and I'm not even sure what I'm supposed to be making at LLH.

Suited connectors are pretty much raise/fold in unopened pots from late position. Personally, I'd usually raise 89s from the button or cutoff. 56 is marginal to bad (for me), so its opponent specific.

In other other positions or facing limpers, you usually aren't going to be able to push people off their marginal hands. They're still worth playing, but only in situations where you're getting good odds to make up for the lack of fold equity. So you'll normally want to limp in behind 2+ limpers in front of you and the more that limp behind you, the merrier. Basically, you're hoping to flop a draw AND get correct odds to chase it.

One possible exception is in late position in loose games. Some books advise raising a large field of limpers with suited connectors to build the pot so they get correct odds to chase with weak draws like overcards, and also to make sure anyone who catches a piece pays you off just because of the size of the pot. The flipside of course, is that you'll also sometimes give yourself odds to chase gutshots and the like... so its probably a more high variance play. I rarely do it.

About non-nut draws, yes, they're worth it. Just dont go capping 4 high flushes in a five way pot. Also, hands like Axs are sometimes worth playing in multiway pots purely for the flush possibility, maybe even Kx. Anything worse usually isnt.

Edit:
PS: I may have forgotten how to play full ring by now. If anything I said is a bit spewwy, someone please point it out.
