I am friends with John Havard of A&H and have had the privilege of trying some of his bows including prototypes. I shoot the same arrows (718 gr 2219) out his bows at different weights 50 to 66 pounds at my long draw and the arrow flight is great. I have a 200 gr point out front which may soften the spine a bit, but his bows were very easy to get used to relative to the recurves I have been shooting. Don’t just let arrow speed be the deciding factor, shoot it a bit and see where they are hitting the target. It is much easier to go down in draw weight than work your way back up to where you are. If not, your son will eventually fit into the bow and as you already know , these bows have held their value pretty good. Getting a peak at the future, I think this company will be around for a long time.
