Here is a bow I am just getting started on, I have it cleaned up and very roughly floor tillered, I just glued on some ipe nocks. The bow is 54" nock to nock, BBO, target weight 50#@24". I copied Marks designs to a large extent with a few touches of my own. At present the bow weighs 19 oz, my projected finished weight is 17 oz. If I go to far below that and start to show signs of stress I will drop the bow to 35#.
Starting with 3 3/4 iches of reflex I don't expect it to creep up as I tiller because I did not glue it into perry reflex. I pretty much formed the wood then wrapped it with maybe 2" of relex induced under light pressure. These have a higher than normal failure rate so I will post as I go and hope it don't break. Target speed is a minimum 245 fps with 200 grain arrow, otherwise just another practice bow.
