I’m liking the expedition Kevlar from Swift. I haven’t butt dragged down many rock gardens, but Kevlar is easy to repair, although you will never return anything to “like new” condition. I’m good with just filling scratches and gouges, even on Royalex. I don’t care about touching up color coatings. Just some Gflex 655 (thickened) and I’m good for 99% of stuff. Soaking some Kevlar felt strands with Gflex 650 to insert into wider gouges is good enough for me. Most canoes sell for their original price after 10 years, not matter scratches and repairs. I made money on a couple old royalex tandems that had some good mileage. Long way of saying forget about repairs and get the boat.
