Has anybody ever bought indo fins (eBay)? They seem to be the templates of whatever fcs model you want, made of fibreglass and are about $100 cheaper than the genuine article.
They don't look great - plain colour - but who cares for that price....
Any good? Worth a punt?

I've had a few of there winged fins. They seemed okay

Sorry no idea other than that..

I've had a set of H2s which were ok, till my nephew far£><d em and a set of Kelly Slater 2s quad/thruster
Both sets needed minor sanding to fix a "hum" but apart from that they work fine and as you said, $100 cheaper.

I've had a few sets and find them ok, they aren't highly finished, have that handcrafted look to them, but I like that.
