Worst PLO Hand

Was playing a Bomb Pot tournament yesterday and got what I would consider to be among the worst hands for PLO, but a Hold ' Em player would drool over.

Rainbow, no runners, the best hand you can make is full house which means that nuts if 4 of a kind and there's still 9 cards worth that can pair higher and beat you.

For you, what's worse than pocket quads that you would fold immediately without even seeing a free flop in a bomb pot?

Cannot think of anything worse than that in a bomb pot situation.
However never fold until you have to.
1 rude to the other live players to know you are out of the hand as your position will always give someone an advantage.

2: 1 in a million times you may be able to steal the pot when your 6 is part of a possible straight flush and no one wants to bet.
