Blast from the past.
The first boards I made were thrusters. 3 deg toe in. Then using angled plastic fins ,reverse 2 deg to offset the toe in .

We had options back then of 0 ,1 ,2 ,3 deg side fins.They were there purely for the safety factor of being able to get home after snapping the centre fin. We were doing dangerously long runs. It was not because we were copying the cool wave riding guys. Although it did look cool. At the time ,we , (freeriders ,were all using those US box football fins. ( remember them ?) I think they were Australian made. And those other swept back versions. They were supposedly polycarbonate, but they weren't, cos they snapped at the base. They were the first fins you could push hard with the back foot. It was a time when rounded pintails were becoming groovy. Before wide boards were a thing. I think it was the start of the feeling of pushing a fin that allowed wide rear ends. Before the long pointer fin. That was also the time twin stringer blanks were good for holding the box. You could never roll a twin stringer box. Add another half a kg.
Those were the days.

Ps, oddly my favourite go to board now is a rounded pintail with wingers instead of cutouts.
Its going to be be the new thing again

Yeah, probably not
