Weight can be a big factor, especially when trekking it solo to the water. I own a fiberglass, but considered the plastics. I like the light weight of the fiberglass, I can repair any punctures easily enough, and I am not on any water around here where punctures are likely to occur. If this were my mountain river canoe, it would be sunk in a heart beat after hitting a few rocks. That is where the plastics come in most handy. Plastic canoes also are very practical for use such as rentals, which take much abuse. I take great care of my canoe so abuse is not a problem for me.
