I think the original designs were meant to be shot with a thumb ring. So there could be some finger pinch issues with a three finger draw unless the bowyer stretches out the design a little.
A year or two ago there was post on paleo planet about some turk bows Adam karpowicz had done and tested on a shooting machine. One was a replica turk flight bow, shooting 126lbs@28. They shot a 250 grain arrow arrow off of it and were getting around 360 FPS. There was three bows in the test and one of them, shooting at 9 grains per pound was getting 205 FPS, both bows were shot with dacron and they weren't completely cured. It would be fun to make one of those with carbon foam limbs and carbon fiber siyas.
