My perfect one piece would be a Hybrid of the 60's era Wing Redwing Hunter. If only a bowyer could get that awesome choclate toned rose wood and craft a riser slighty longer (60" to 62") than the original 58 "so you wouldn't get the finger pinch at draw lenghts past 28".
I have Redwing hunters at 45 and 50 and 53 and they are very smooth. fast and quiet. The grip is hard to improve on.
The recurve geometry on the RWH is about as close to perfection as God could come up with and if he wanted a bow I think he would apprecaite a Red Wing Hunter.
But He might not listen to me all the time.
One thing about 58" bows is that they are great in a tree stand and also you can shoot them when you are sitting on the ground without the limb tip hitting.
also, the tiny little sculpted tips of the classic RWH are so pretty if i ever break my bow I will make jewelry out of them.
