A few of us ran BR down through Rigo at the very end of last season at somewhere around 100. We did it play boats and actually had a good time. We just kept getting out, walking back up and running everything multiple times, with whatever different lines we had to choose from at the level. The pin potential is certainly a factor, so don't be complacent just because its super low.
