Advice needed for football pool!

I'm in a weekly football pool where this weeks payout is $2110. Me and one other dude are both undefeated going into tonight, we're both on Green Bay, so it's going to come down to points. I have 48 and over and he has 47 and under. My question is, should I bet ~1k on the under (currently 48.5 -105 or 49 -115 at my book) or should I just let it ride. According to what I've found the total lands on 48, 3.02% of the time, which would be the jackpot for me. Any advice would be appreciated.
