1 Best place to buy fins online.
2 Is / does anyone running or tried quad keels ?
Thanks

1 quobbafins.com/ of course :-)

Otherwise, I advocate buying at the shop, local or online, that you would like to keep existing in the future. Most fin brands impose a standard retail price, so the price difference will not be huge (mainly on the port). What is important is to help the shops you like.
For me I wont care if all fin makers disappear as long as Quobba is still there :-)

2 I found keels great at low speed but quickly become overfinned. I'd rather use the C-Drive twin fins plus small rear quads, they have nearly as much drive as keels, but stay nimble in the power.

Shapers fins on the goldie have a great range - I always find their large short board fins work well in the SUP's- always great to deal with and good prices and quick dispatch - the MB large and Carbon Flare extra large are worth a look. A couple of US box centre fin options for SUPS as well - got some new MB medium larges in my F Skate miller and they work a treat

Simple surf in Newcastle had some billy basic carbon flare style large thruster sets in dual (fcs) and single tabs (futures) for a great price - run them in my ECS 7'5 slab and work nicely from knee high up

Happy fin hunting
