Shuttle Pipes

An older friend severely injured his collarbone to such an extent that he is no longer able to handle the full weight and exertion of a great pipe. He has also experienced some hearing loss. I think a set of shuttle pipes would be just the thing to allow him to keep playing, both because of the lighter workload and because of the nature and position of the drones. No preference, regarding the number of drones. The only type of shuttle pipe I know of is made by Walsh, but the brand is not a make-or-break thing so long as the set is reliable. I keep just missing listings, so here’s hoping this works.
