I'm sort of new to PLO so bare with me. There are some very soft 2/5 and 5/10 PLO games where I love, most of them play very deep and the players are very loose and bad. It's very hard to get isolation and most pots go 5+ ways to the flop. Obviously, these are amazing games.

In position I essentially value raise a wide range and limp behind some hands that have nut potential but aren't great (Axxx with an A high suit, JJxx, QQxx type hands, etc). It's pretty easy to play in position. 

In EP however, I've been battling with the idea of open limping as opposed to open raising pre. Here's a couple arguments I've come up with:

1) Open limping seems to encourage the bad players to limp behind with garbage in EP and MP, while raising seems to fold out some garbage hands but I still am usually going 4-5+ ways to the flop. My assumption is I'd like those garbage hands in the pot against most of the hands I'm playing UTG.

2) Open limping encourages raises more than open raising. People seem comfortable making raises or even making small juicer raises (lol I know) when people have limped, but are not as comfortable 3betting. If I can get some limps and a raise, I'll be able to pump it up huge with my strong hands. While if I raise, I probably won't get as many opportunities.

Do you think these are valid? Coming from a hold'em background, it seems dirty to open limp at all but I feel like it might be a superior strategy in these types of games where the players are so poor and unaware.
