All-ins in Omaha

Based on my current level of experience in Omaha, I've formulated a pretty simple all-in rule: never go all in on a draw. That is to say, if you have four cards to a straight or four cards to a flush, you have no business going all in. Period. Full stop. The end.

Last night, I didn't have to put this rule to the test. I folded early and often until I got a legitimate all-in hand:
