Hi, I need some advice about new fins. After a half year pool training (and soon aida**) with snorkel fins I want the Cressi gara 3000 ld for some open water adventure, not so deep, just between 5 or 15 m. Now I've seen the leaderfins ice middle and think about what is the better choice. Maybe after some time and higher level I can easy change the leaderfin blade. Which footpocket is more comfortable? Another point, the Cressi are just plastic fins, the leaderfins are fiberglass. What do you think is a better future interest
