Thanks for the info! We went to a few more pool stores today. Pretty confusing trying to figure all this out. I'm leaning possibly towards a Sharkline Morada RTR 54". The structural components are mostly resin including the top rails, end caps, bottom plates, and bottom rails. The uprights and walls are galvanized steel. I'm hoping the mostly resin is a good idea?

However, when we went to the last pool store that sold Doughboy (which seemed overpriced to us?) we asked why one of their "top of the line" pools did not have resin bottom rails or bottom plates. They told us that they only do galvanized steel bottom rails because resin bottom rails can crack and break in a cold climate (we live in Michigan). Is there truth to this??!?! I had never thought of that.

thanks!
