The Royalex material on the Pack is really tough. I took the seat out and use a plastic fishermans seat purchased at Walmart on the floor of the canoe and a double bladed high quality paddle - The same set up works well in the 119 but better in the pack. Extremely stable.
I found out that recently they quit making Royalex so I purchased a new Pack canoe from the local REI store - it was the last one in stock.
The Pack canoe is truly the best and most enjoyable purchase I have ever made.
