Deepstacks - how much can I afford to pay for JT98ds?

[Moose]

Hey all,

just got back from a 1/2 PLO game, the stacks were quite deep as the action was fairly heavy. Everyone had at least $300, most players bought in for $500; I had $1300 and the player to my right had me covered.

One limper, player to my right raises to $10. I reraise to $25 with JT98ds. A cold caller, a reraise to $75, THAT gets cold called, and the original raiser now raises pot to $300 (the exact cold callers and their position is a bit hazy).

Should I dump the hand here? If I call, I still have $1000 to bet and position on a player who can double me up and I am 100% certain that he has a big pair, making my hand incredibly easy to play?

Actual results follow.
