My handles are very similar to yours. Handles are 1” wide, fades are 1-1/2” at widest point. The arrow will point hard left when sitting on the string at brace. I shoot a 12 strand D97 string, and have a full 28” draw.
Shooting DF, I cut my arrows 28-1/2” to back of point, and run 35/40# spine out of my 46# bows,and 40/45# spine out of my 50# bows. This is with 125 gr points, and 3-3” feathers.
When I first made the switch from recurves to this style of selfbow, shooting instinctively, I would always shoot left 4-6 “ depending on shot distance. I had to learn to look down the entire length of the shaft consciously to get things moved to the right. Eventually my brain recalibrated to subconsciously point the whole shaft to the target, and not just the end of the shaft.
Not saying this will work for you, but just my experience.
