Ok. No falmes please.. I was Thinking.. What if I cut the space on my Aeris Velocity fins. I'm not going to do it... but... I was just thinking. If I did, would they work almost like the Velocity Duo split fins? I know I'm not the only idiot who has thought of this. I have looked at both fins in my LDS. I think it just might work. I'm not going to do it but.... I was just thinkning. My dive buddy laughintom said I'm crazy, or was it cheap? I don't remember. Do you think it might work?
