In your opinnios what is the best shape of rocker?

Im talking about shape generaly not about ammount of rocker

Is better elipse rocker or just circle or something irregular with steps?

IMO after just brainstorming not real testing regular circle ist best.

Becouse flattest tail part witch means fastest shape.

Thanks for comments

Tom

I agree I think that the best rocker shape is a circle shape for 2 reasons.
1 as you said it has a flatter tail.
2 no matter where your weight is the rocker is presented to the water the same way, for example if you have a flat spot in the middle and ride with a lot of back foot weight what angle is the flat spot at ?

cheers
