Unbalanced limbs

Thank you. Appreciate the information.

About tiller, I thought that it’s bending too close to the grip but compare to the virtualbow model with evenly distributed stress it’s Ok.

Yes, it looks about right. Although i have no skill to read that graph…
In the end what determines the limits is set/deformation. If the bow is holding up and performing well, then its good. For flight, the consensus is to have more bend near grip. Like your bow basically.
