basic omaha 8/b - raise or call

[nicky g]

online omaha 8b .50/1 - it's the river and there are still 6 in the pot. i've made the nut flush, but alas have no low and there are a million out there. somone who i have reason to think has the nut low bets, and i'm next, with 4 players to act behind me. should i just call, hoping for a bunch of calls behind me, or raise, hoping a few players will call anyway, but increasing the risk that i'll only get a call/reraise from the nut low?
