Hi
Yes, I use a thumbring albeit the focus should be more on the bowhand. It seems to me, these bows need some special treatment.
A Turkish style bow made larger for my draw is far away from the originals. Their advantage are light arrows, but you can't make 33" arrows with the weight of the 25" ones used in Turkish archery back in the day.
A longer bow would most likely have a slower cast with light arrows as well due to the higher weight of the moving limbs.
Therefore I look more into Crimean Tartar and Persian style bows. They were longer ntn, allow a longer draw and had more massive arrows.
