The ScubaPro Jet fins...the one with the paperpunch holes IMO are one of the best fins of all times. I have two pairs, one is fairly new and the other is at least 30 years old (came in a box of old gear). The rubber on these fins are very pliable---unlike other "jetfins" that I have had before. As you have probably read in other posts, the jets are king in currents and with lots of bulky gear. We have also found them very useful when running DPV's--
