This is the point for me when the straight edge is king. Run a 4 inch item along the belly. It can be anything as long as it is flat and straight along one side. a 4 inch long 1x2, 2x2. A piece of metal, anything that gives you a good straight edge on it. Run it along the belly from handle to tip while the bow is drawn like it is in your pic. Any spot with little or no gap needs to bend more. Mark it with a pencil for scraping. Any spot that has a gap wider than what's around it is bending too much. Mark that spot as don't touch! Do that on both limbs. If you keep the gap even from stem to stern, the tiller will be right with no hinges or stiff spots. A little common sense is needed. The areas next to the grip and nearing the tips wont bend, right? So they will fade to flat (no gap). Now you can single handedly get that bow finished. Asking for tiller advice at this point from 20 different people will get you 5 different answers and that's fine. Which answer agrees with the straight edge? That's the one to follow.
