I realize it was a figure of speach, I catch myself all the time doing similar. Sorry that it sounded so harsh. The Jet is a great fin. They have been around a long time and I recently learned that they were first introduced around 1964!!! My main and dominant beef is that I simply do not fare well with any of the strap type fins. I should not single out just the Jet, other of the strap types kill my feet and arches just as fast. I do in fact have a pair of Jets and some old Rockets etc. The Apollo fin I can give no guidence on ---sorry---but I think people who generally like the solid "paddle" type fins might find some adjustments to be made in kicking style with a split--I believe that the Jet is a very versatile fin, perhaps more so than any other. If Jets came in a full foot they would probably be on my feet. Good luck with your research. N
