Puffer Fish has it right. I don't use splits, but I recognise that they offer speed (example: Apollo Bio Fins Pro). For a solid fin try the Mares Quattro Excel Fins. Jet Fins are slooooooow...

SparticleBrane:The next question is--how did you know it was a 1.5 knot current? Was this just an estimate? If not, how was it measured?
Split fins wont take you anywhere against a tough current, also if u ever use them remember to do small and fast kicks.serambin:On a recent trip, I found myself in a current of about 1.5 knots. This took an extra kick to over come, so my thoughts went to better fins (as opposed to better conditioning or strength training). I use a pair of Tusa Liberator fins. What about split fins or rocket fins or CO2 powered fins (or even nuclear powered fins)? Is this an area worth looking at?

SparticleBrane:And what do you base the estimate on? "Oh...that looks like 1.5 knots?" You need to use something more reliable than that!
6-second rule for estimating current:
"Current speed (in knots) can be estimated by determining the distance an object travels (in feet) in 6 seconds, divided by 10."
Example:
If the distance a piece of seaweed floating on the surface in 6 seconds was 7 ft: 7/10 = 0.7 = 0.7 knots.
Basis:
One nautical mile = 6,076.11549 ft. Let's round that down to 6,000ft for ease of computation.
If something travels ~6,000ft in one hour, then it was moving at approximately 1 knot, yes? Now just use math:
6000ft/hour = 100ft/min = 10ft every 6 seconds. 10/10 = 1 knot
