Really? Lowest divison? I've never heard that advice before
Maybe for a complete newbie or someone with very little confidence in your game...
From the little bit I know about you emiller, I'd say intermediate. Rec is people who play twice a year or are complete virgins. Intermediate will be just like playing a round with your buddies... Everyone will try their best and play competively, but usually everyone is encouraging and want the other players to do their best as well.
You obviously are experienced enough to list a quality bag in your sig. You're intermediate IMO. It's laid back and eveyone will help you out with rules and stuff.
Wait until you see the scores and someone from intermediate could be on the top card in advanced and 2 people in advanced could be on the top card in open.
I say play up if anything. You'll play with people who you would like to play with again.
