I guess I really don't know myself, but I like to tiller them to have a bit of reflex at the tips at fulldraw. I just like em that way, a bit better string angle at fulldraw might make for a bit smoother draw, I don't know. I mostly just like the looks of em that way, haha. I tiller them that way by laying off the outer tips when scrapping for the most part. I know I see a lot of people just tiller them out to look like a normal flatbow at fulldraw. And then a lot of people tiller them out to have stiff outer limbs, like a holmegard. Which I guess would allow some string angle advantage as well. I am also curious about this, at it seems quite varied.
