If you enter a qualifying bow into the December BOM your name will also be entered into the end of year giveaway. I really hope to see a huge BOM turnout this month!

I also like the curvature graph—you can see exactly where the bow is actually bending.

Yes quite helpful with reflex/deflex and other profiles that are hard to judge when looking at the bow on a tiller tree.

Here are the results I got from VirtualBow. Remember, no set, idealized situation, although 5 % damping in the model, 10 gn/lbs arrow, every reflexed bow’s tips are 100 mm (4") behind the belly side of the grip (thus about 70 mm from the back).

The deflex–reflex design performs well, while a handle-reflex design does not. The reason model 4 performed poorly is that the recurves didn’t open fully even at full draw; the string was still almost in contact with the base of the recurves.

Willie: Yes, in VirtualBow the ability to visualize the stress curve is a great feature. I also like the curvature graph—you can see exactly where the bow is actually bending.
