I was looking at the fiberglass fins4u because they were around $100 and you could pick different rigidity. Are those any good?
fins4u are Leader fins marketed to the UK. You can see the label on the fins in their website, it says Leader. Keep in mind all the prices are in British pounds, so if you see 100 that will end up about $160, plus whatever shipping is from Europe which isn't cheap.
Leader fiberglass blades are very poor performers at any stiffness. I wouldn't recommend them even to replace plastic fins. Leader carbons (really carbon/fiberglass sandwich) at medium stiffness only, are decent entry level fiber fins. Soft and hard stiffness are poor performers.
The Leader carbon fins medium stiffness are available at Leader Stereoblades Waves Carbon - FreediveStore.com for $160. Unlike other spearfishing gear shops
we don't rebrand the Leader fins and sell at an inflated price. At this time included in that price we also install Speardiver tendon rails. The Leader tendon rails are poor quality and do not fit well in footpockets.
You'll need to get footpockets. I don't recommend the Leader footpockets. They're a copy of the omer Stingray footpockets which would be alright, except they're manufactured too soft which results in poor energy transfer to the blades.
