I was at the Boost Mobile Pro today and noticed that most of the pros are using glass on fins. Is there that big of a difference? It is my understanding that the biggest demand for removable fins was actually from surf shop owners who wanted to be able to hold more boards, not from consumers. Granted, having FCS, etc. would be good for traveling, but how often do most surfers have to fly anywhere, once or twice a year (at the most) and in my case, about every other year (Hawaii) and then I usually rent boards because the selection is so good and it's cheaper than paying 80 bucks each way to ship boards on the plane. I digress. So, what is your opionion on glass on fins? I think I'm going to go with them from now on. Reminds me of the good old days.
