Specialfins hybrid review
After a long long decision process, I got my hybrids (hard) several months ago but only got to use them in diving water June 1. Having an analytical bent, I thought I could get a good comparison of the hybrids and my old Cressi 2000 hfs. Turns out comparing fins is extremely difficult. Leg strength, kick style, foot pocket fit and the conditions you test in make a huge difference. In the pool, I tested kick cycles and times underwater and on top, 25, 50 and 500 yards. I found the hybrids to need one less kick cycle over 25 yards and to be about 8 percent faster over all distances. On the 500 yard sets the hybrids were noticably more efficient, but I couldn't figure out how to quantify it. My legs were dead with the cressis and tired but good for more with the hybrids. One other area that is important to free shaft spearos, the initial acceleration of the hybrids was much better.
At that point, having heard such great things, I was a bit disappointed with my new and pricy fins. After conversing with Jyri and some other DBers, I decided that getting used to the hybrids and doing some ocean diving would improve my results. This turned out to be true. Apparently, my legs were reallly adjusted for the cressi's. After using the hybrids for a few months in the pool, I noticed my times getting faster. When I got a chance to actually go diving, the hybrids were fine, and seemed to tire my legs less even though they are a stiffer fin. In my style of diving, this is hard to measure. I suspect that the difference is considerable. Today I got back in the pool for some testing and found the speed difference had increased to 10-12 percent. Interesting that the cressi performance increased slightly as well. The hybrid's characteristic snap makes for a very different kick style. I don't think I have mastered it yet and expect a continued improvement with time.
I am much happier now. 10+ percent increase in speed for the same effort, noticable reduction in the amount of effort needed to maintain speed, less strain on my legs over a day's diving, much faster acceleration and much better on the surface performance are worth paying for. The last item is something I did not care much about, the cressi's seemed fine, but it sure grew on me. The blades stay in the water better, they're quieter and not having to turn a little sideways to go fast is really really nice. If you want to whale on them, turning a little is still necessary to keep the blade completely in the water.
Unirdna supplied me with a set of kelpie mediums and, for a while, I thought I had found my fin. They just felt better on my feet in the ocean, can't quantify it. However, in the pool the hybrids were definately superior, with the kelpie's performance coming in half way in between the cressi's and the hybrids. In particular, the greater efficiency of the hybrids was very noticable. One of these days I would like to try a set of hybrid mediums.
A few other points:
lots of DBers helped me with blade and foot pocket choice. Thanks to all, very much.
Unirdna tested my hybrids against his kelpie hards and found some interesting things. I'll let him describe, but if he claims to have beat me in a race, I have a different opinion.
I chose the sporasub because I wanted to wear it barefoot. That and sizing worked out fine. They aren't quite as comfortable as the cressis but I think that is mostly because my callouses are in the wrong places. That will change.
After wearing the sporasub/hybrids for a while, the cressis feel really blah, much worse that their performance actually is. Fin comparisons are tricky.
Special thanks to Jyri and Specialfins for putting up with my indecision and providing outstanding customer service, don't think I have ever seen anything like it.
