NL 2-7 Lowball Question

[IronDragon1]

Scenario:

Late stages of a KC Lowball tourney

You are the shortstack (~5BB) and dealt J-7-2-3-4 in MP1 with and push all-in and folds back around to UTG+2 (aggressive chip leader) who quickly calls and stands pat.

Do you stay pat with your Jack or break to draw?


NOTE: I really don't have a concrete answer, I'm just trying to get perspectives on the subject
