I have been hunting and shooting bend in handle bows for maybe 25 years,,,
the chronograph,, will show you they are effecient,,
it may take a bit more practice to get used to the no handle,, but for me,, I love the way they shoot and handle,, and also lets me use a shorter piece of wood if need be,, I have a handle bow I use for elk hunting,, its 66 inches long,,,so I make and shoot both,,,,
at this point,, I dont reflex the tips much any more,, I reflex the whole bow and get the performance I need,, Ive gotten a bit lazy,,
I see no down side to the design you used,,just a matter of preference,,,as the bow gets shorter,, the design becomes more suitable,, as the bow gets longer,, a longbow design or handle bow works great,,
I think you got the wrong idea bow makers dont like this design,, I dont think thats the case,,
