I just scored a couple of new old stock Redley Fins off of eBay. One is black/blue and the other is all black. They still have the powder on them! I've always wanted a pair since I borrowed Danny Kim's pink/green combo back in the early 90's at Sandy's.
Funny enough the pair I have now is the first I've tried, been at it for a while so it's kinda ironic since the maks are so popular, love 'em though, noticeable difference in thrust compared to what I used to use.
I've had the chance to try both Redley fins. The all black ones are stiff and the black and blue are a softer fin. Both are nice, but they've been in storage for so long with the original powder on them that the powder is almost permanent! Oh well. I'm digging them for sure.
