For me, an extra 9 inches of fin would prevent me from getting position in many of the type of shots I do. Swell or no swell, longer fins make it more likely to hit something in the areas I like to dive.
That being said, I would like to try free dive fins. I am short, thin, small feet, weak legs. I can swim fast, but that is due to kick speed/frequency, not power. What would you recommend ?
If you're looking for under $200 you're looking at plastic blades.
OMER Stingray Fins Here is Omer's. They have a very comfortable foot pocket. The guy at this store, Dan, is very knowledgable and helpful. Contact him and send your foot measurements.
FIN BLADES | Riffe International Here's the Riffes. The blades worked well. Not as "whippy" as carbon but much cheaper. I don't like the foot pockets though. Very hard. If you're using a full neoprene sock though they should be ok.
Cressi Spearfishing Fins freediving long fins spearfishing extraordinary thrust comfortable foot pocket flexible cold water Never used these but one of my buddies has them here. He goes all day with them.
I used Riffe Silent hunters for a couple years. I gave mine to my 74 year old dive buddy who swore by his ScubaPro Jets. He's now a convert.
The Omer Millennium is a very comfortable pocket. I put them on my Riffe blades and it's much more comfortable. I also put Beachat foot pockets on another set of Riffe blades and it worked well.
When I first got the Riffes, my buddy, who was in much better shape from running, was still using a Beachat scuba fin. Similar to full foot Mares Quattros. I had a pair also. When I got the Riffes, I could easily leave him behind in currents. We noticed the difference right away.
Now, 12 years later or so and a few sets of fins and pockets. (I like tinkering and adjusting things) my son and I found Moana blades to work the best. (there are others we haven't tried though) Other free divers I know agree. But they come with a Pathos foot pocket. It's comfortable but I have a high arch and it's a bit flat. I had to heat the pocket and stretch it a bit on top of my toes. Using those fins, we required 20% less leisurely kicks on our reservoir to do a lap than any other fin.
Speardiver fins are very nice too. He has different stiffness. But now we're talking carbon and around $375 or more.
Cressi or Omer should work for you. Hope this helps.
