Thanks for all the info and advice.
I definitely want a dedicated solo and a tandem.
The purpose of my trip to the canoe shop last weekend was to look for a solo. My wife was along and felt the weight of the tandem wenonah's and northstar's and said we need a lighter tandem. We are heading to the Adirondacks in August for 8 days and she remembers carrying one our royalex tandems we took a couple years ago. This trip two of our kids are going so we were planning on taking two of our Mad River Explorers (both royalex). Our youngest is 10 and my wife was thinking if we got the Northwind 18 (18'9") we could take most the gear and her. Our 15 year old boy wants to take his kayak or my solo canoe (also royalex). I'm hesitant because I'm thinking of other future trips. When it's just the two of us do we want a almost 19 foot canoe? Yeah its light but it's a big boat! I think we would be better off with a 16' wenonah or something similar.
Yellow canoe said a lot of things I was already thinking....I'm getting older so lighter is definitely better, and if it's a choir/hassle to use it won't get much use.
