I'm considering a new pair of fins.... since changing my drysuit, my feet no longer fit into the foot pocket of my trusty old ones..... so my considerations are: Force Fin Pro's (Expensive, Take some getting used to) Twin Jet Max (Quite Heavy, reasonably priced, possibly under powered) Avanti Quattros (Cheap, powerful, but can be hard work) Apollo Bio-Fins (Not cheap, Heavy!, difficult to source in the UK?) To be honest... the geek in me quite likes the idea of the Force fins.... but i've read so much about them and how they require a "new" finning technique, i'm kind of nervous about splashing the cash without trying them! And i quite like the look of the Bio-Fins too, but being 100% rubber, i'm guessing they're going to be toooo heavy. Fine in the UK, but too heavy for travel! As i don't know anybody with them, borrowing seems not to be an option.... So i wondered if any of you guys n gals use or have used force fins or bio-fins, and what your thoughts are, pro's, cons etc?????
