If I had space to keep a trailer I probably wouldn't consider the Sportspal and would go with the Old Town or something similar. Unfortunately, that's not the case, and whatever I purchase has to go on top of my vehicle. I'm also taking into account I'm in my mid-60s and want to use whichever canoe I purchase to fish with during my retirement years. I will be attaching a trolling motor and kayaks do not appeal to me.
My understanding is the Sportspal is heavier gauge aluminum than the Raddison and has superior construction. That said, there is considerable food for thought presented in this thread. I'm not 100% sold on the Sportspal and am still researching but I've yet to come across any negative reviews or discussions of problems with the American made craft so far.
