Lookin good Arvin.
Seems you have some extra width but will set your tiller weight goal for the same draw weight and length as the record bow? That will give you some margin for the experiment. It would be cool if you dont experience the usual inch or so of set you report for some of your all Osage bows, and hopefully the boo will perform in front of the chrono.
I do think glueing in the reflex with a lam will make a diffefence
