To me there is something more graceful in the lines of a one piece, or two piece that looks like a one piece, bow. Not all of them of course. some just look like a stick with a thicker middle. But some, like a Mountan Monark or my Primal Tech long bow just look like they are part of a picture regardless of the woods or scratches or . . .
Then you have the other end the the Black Widow bows that shoot so smooth and consistent yet, other than the PSR and PL just look like clubs wth limbs.
Some, like a Primal Tech 3 piece, at least try to do something about the disproportionally large mass of wood that looks like it is at odds with the slim limbs but not all do or can I imagine.
Some bowyers have a something a little more that challenges them to push the boundaries and take what is just a tool and turn it into a piece of craftsmanship.
Still, regardless, I've never seen a 3 piece bow that could rival the lines of a well built one or two piece. Even the uglier ones like Bear bows.
