I need to buy new thruster fins.

What are the general views of the brands on the market? Are any brands considered more premium than other budget brands?

Black Project
Tectonics Maui
Maui Ultra Fins
Maui Fin Company
K4

K4, these fins aren't so likely to be damaged, being shorter than the center fin. I use K4 on nearly all fins. Continued development in stiffness , profiles etc. Very reasonable price.

Black Project Fins, I have a few very nice. PRICY
Maui Ultra Fins, I have some also, very nice.PRICY
Makani, I have some centers, and singles, sold the thruster sides. Semi moderate price in USA.
Witchcraft fins, very top in G10, and RTM. Been a while since any purchase . Price with delivery on higher side.
CNC , fins pretty well custom from North Carolina. More weed based, like Tectonics, pricy. Very Top.

my Order would be : K4

CNC
BPF
MUF
MAKANI

I have fins in G10, custom made by a Surf Board co. In Hawaii, made in ProBox base, that work brilliant.These I use on tri - fin conversions from a single.
