Start to I sow it with my own eyes.
Probably a bit late but I have only just joined. I have been useing a pair of force fins for the last 10 years and I would never go back to any other type of fin. They are good for most types of situation and don't stir the bottom up as much as others while giving you all the power you need without the strain on your legs. If you can find a pair try them, although you may need a couple of dives to get used to the different way of useing them. Cheers Ken.
