We have been canoeing for over 20 years. The Clippers are good boats and the models you suggested are appropriate you would probably be better off with kevlar particularly if you plan on many portages. Royalex is better for white water. We have an 18' Wenonah Sundowner Canoe 65 lbs in fiberglass which is similar but made in the USA. They are easier to paddle the longer they are. You might also want to consider the Mad River Explorer from Vermont available in kevlar, Royalex and Fiberglass. Usually there are a variety of layups having different weights. Boats last a long time so go for quality.
