drawing to the nuts also means if you have the nut flush draw on a paired flop your best bet is to fold there, mainly in a hand that contains four or more people. Remember that nut flush draw isn't really drawing for the nuts on a paired board.
Lead bet more often with your draws and your real hands if people won't stop pot betting in position, theres not gonna be much bluff raising in omaha compared to hold em. People will bluff raise you with draws that may realistically be favored.
The reason you need to try to make sure your 4 cards are coordinated is because you always want to have outs to a redraw just incase your in a scary situation, ex:
you have kqj10 flop comes k j 7, you bet pot and get raised. villain could have a wide range of hands here pending how he plays from a super straight draw, k j like you, a weaker 2 pair, or a set of kings jacks 7s. Say your not sure if he's bluffing or not but you think your ahead, you want another draw just incase your wrong and this case you have outs to possibly make a boat or the nut straight....
Now consider that same flop but you have kj54. You still have 2 pair, you bet it pot and get it raised. Now your read has to be spot on here, because all you can beat is a weaker 2 pair and a bluff here, if the villain has a mega draw you may actually be behind percentage wise on the flop, and he's got more live outs to every straight card he may need because you don't have any of the cards he may need. Note the difference between these 2 hands, this is a situation that happens somewhat often.
that advice mainly towards regular omaha, I'm not really to fond of hi/low because the low is so often used as a bailout, and it can be good with donks and fish sometimes, but they get bailed out often regular omaha these people can't be bailed out by a split pot because of a low. Plus smart omaha hi/low seemingly requires you to do away with a lot of good regular hands like for example kkQQ, thats not necessarily a good hand in hi/low. The Main point of omahi hi/low you want to "scoop" or win both hi low pots, only way your gonna really do that is play coordinated hands ranging from a-8, so every thing above that is heavily devalued in hi/low, this is the opposite in regular omaha.
