Toe-in and symmetrical foils

If you are building a new board and want to use the Wavegrinder 5.5 as side fins in a thrusters or as all four fins in a quad, we recommend zero toe-in.
The diagram below discusses why zero toe-in and symmetrical foils make more sense according to hydrodynamic laws. That being said, most of our test riders have used these fins in standard thruster setups and all have reported great performance. They work great in quads!
