I actually have a nice selection at the moment. Through a couple of sample packs I purchased up front, an assortment I picked up from
www.tryablade.com after buying my 37c, and a couple of PIFs that I've won, I've acquired over 100 blades. See selection below. I'm in pretty good shape for having selections to try with the Fatboy and the DE89 that I just picked up.
Green means they're in my top 3 so far. Red means I still haven't tried them in my 37c since making it my go-to razor.
