Is there any particular benefit to useing split shaft pots? I find the knobs designed for them to be kinda annoying to work with. Either you're fighting to get them off or fighting to keep them on. The middle ground, where they hang on tightly but slip off easily when you pull with reasonable force, seems difficult to achieve. Plus, if it's set slightly too loosely, then you can overrotate which will often strip the threading of the knob. I much prefer a solid shaft with a tightening screw.
