rough ideal on rat size to feed a bp question

Ok i gor last weekend a bunch of rats( many different sizes ) and I in the middle of freeseing them off and vaccaum packing them.
I packaging them in a rough 300-600 gram packs so far I getting about 2-4 in most bages and not gone over 400 grams.
but my question is I have 3 so far ( prolly more) that are goingo t be single rates in the 350+ gram range. I don't have a bp over 300 grams yet so should I just freeze it and hope that I get snakes that heavy in the usable future forthe rat or find a person neding a rat this size to offer their larger breed snakes. I goingot have enough for at least 5-6 meals with what I have live too from rats , since I got rat litters dropping left and right right now.

I need tofigure out what to do with my retired breeder, and such since I no longer have my redtail ( should never got rid of her even if she was too much to get out of the floor for me.)
