Smashing idea mate!Lynn wants me to move her pegs forward.
Would you offer an integrated unit, i.e. a non-convertible model? Sort of like leaving material on your 'Holes Solo Finishers' so the peg could be mounted to it in the same relative position as your prototype? Those that generally ride solo, never know when they may get lucky!
Can you hear me across the pond in Northampshire? 
Thus a second reason for a non-convertible model.
