I'm new to Scuba and when I was at the LDS getting all my gear, I was recommended split fins and went with them on that recommendation. Since doing a few dives now, I keep hearing everyone say I should use non-split based on my leg strength. And I did notice having a little trouble swimming in a river current recently with my split fins. I do have considerably greater than average leg strength and used to be on the swim team when I was younger, does this mean I should be using a non-split fin? If so, what do you recommend? Thanks in advance.
