I like the bendy handle.
It fits my style and with that style,its like you said,a stiff riser is a waste of wood and length.I believe many are uncomfortable with the working handle,due to the way most grip a bow.With the full grip most use with a static,its understandable why they are of that opinion.I use a minimal grip,with the bow handle,resting on the meaty pad below the thumb and the first,second and third finger tips resting on the bows back.Its more of a pushing technique,than a grip.with this style,a rounded or built up grip is a cause for more of a chance of torque,in my shooting.With this style,i need no type of arm guard either.
