Who says you must carry the install tool in your repair kit?
Take off the hose clamps.
Take your oars and P&C's to the local hydraulic shop and have them install the punchlocs.
Throw your old hose clamps and a screwdriver in your repair kit.
(You already had spare hose clamps and a screwdriver and some duct tape, right? Right?
Gear breaks. It doesn't break every trip, but you should expect it and be prepared for it to happen. Those punchlocs might run 3-4 years before needing a repair. I don't see the issue, especially if you're carrying a spare hose clamp or four in your repair kit.
I am not a P&C fan, but to each their own. I'd love to see my friends running P&C's to have these on their oars so I don't get my hands and legs cut up helping them rig or reflip their boats!!
