Has anyone other than me took the force draw and labeled the numbers marked on your bend profile chart or plan. Then tiller to force draw at each bend profile. This can double check  your wood properties possibly. It would be after the fact but possibly teach you something. When I did that it was pretty amassing to me how accurate the design was. Doing that in a selfbow is a real challenge. Because of the unknown crown. But tillering to force draw and bend profile is the answer to the unknown in my opinion. Please correct me if I’m wrong.

I am not sure if I understand you correctly. Could you please give an example? I am not sure how the draw-force curve can be involved, because the bow is overweighted during the tillering process?

3 and 4 look the best for me too.

Thanks guys, shoulder is a little sore this morning but he said it would be for a couple of days then all should be good. Ya Pat, it dose look a little different but as you said at least they ant on the buildings. Thanks BJ, love working on them skulls.

A thousand Quatloos on number 4!

Interesting question.

I'd have to go with number 3 as I'm not a fan of whip tillering at all, really dislike how it looks and feels.
I've found stiffer outer limbs especially when Eiffel towered like in your depiction are much better when left stiffer and barely working.
Additionally I've found whip tillered tips to reduce early draw weight and lower performance and arrow speed though this is with my limited testing
and admittedly biased perspective.

The performance aside durability wise it'd be safer to have the widest part of the bow bending more and storing the most energy. 

I'm sure there are situations like the deflexed willow bow tips in some native American tribes where whip tillering is more advantageous
but for hunting use I believe they'd only be a negative.

That's a great program you've used for simulating the bows draw, would you mind sharing what program you used?

Cheers
