Nice to see you back on here Rig!
After all of the problems I had with my Sporasub Pure carbons, I switched to C4's and my Falcon 30's are still going strong. I like them a lot, but have added a pair of ICE fins for summer time spearing.
Ted is still using his Special fins and has only had one problem with them so far- a tip got smashed going through baggage claim in the airport. He glued it back together and it's still holding up strong. I believe that Sven sold his Specialfin Hybrids a while ago. I had a chance to use them and they seemed pretty nice to me- although a bit pricey.
Not sure about some of the newer fins as mine have held up so well I haven't thought much about switching- except maybe selling my monofin and going back to a pair of C4-80's.
