Hello, I thought I'd throw my .02 in here. I started out using V-16 and quickly realized that I enjoy using a frog kick almost exclusively and was really having to work hard with the splits. I bought some Jets and also some old Rocket fins and liked both, however when I purchased my dry suit, found that the rock boots did not fit the foot pocket.
I found a LDS that carried the Hollis F1 fins and had taken a rock boot in with me expecting to need a XXL fin and was suprised to find that the boot fit the XL. (Size 11 rock boots) The fins also fit well with my wet-boots, not as snug as the rock boots but not sloppy either.
I realize these were not listed in the OP's choices but wanted to let you know my experience trying to find a good non-split fin.
