Hi John,

My frame design differes from the Warrior trike and that made that I can change the seat angle.
I can lay it down or set it straight.
So that is why I was asking what a good angle is.
I have now an image on my instagram from my design.

I understand that on the angle like the warrior, you don't need a headrest. But as I change the angle, I think it's needed.

I was afraid that a headrest would bring the shocks to your neck. That's why I doubt to have an extreme angle as some race trikes have.
Also was I looking ad a material that flexes so it absorbs the shocks.

But I think that what you say, that the angle of the Waarior is good. I can also change it if I don't like it.
A bit more straight, is I think also better for touring.

Thank you.
Emiel
