I hate to be a stick in the mud Brent, but given only a couple shooting sessions at most, I'd be wanting the same exact release. Just the difference in length between the jaws and trigger between those two releases could cause issues (going to affect your anchor point and/ or effective draw length)

If it were me, I'd order a Mongoose from Cabelas overnight or what have you, so it will be back by the time you return from Atlanta.
