I'm looking to install a new 15' round above ground pool. I live near Chicago so we obviously deal with cold and freezing weather for parts of the year.
I was originally quoted about $3000 for the Embassy Pools Coffee Creek deluxe pool kit with 20 year prorated warranty. Just have a brochure so no links to an online URL.

I'm wanting to use a SWCG as well which they don't seem to have salt friendly pools in stock. They quoted me $3899 for the deluxe pool kit of an Embassy Pools Silver Interlude Premium Salt Friendly Pool. So $900 more for just the pool (equipment, liner, etc. is the same)

Obviously, the difference appears to be the resin verticals and resin bottom rail. And this one has a 100% non-prorated warranty on the resin parts and bottom rail w/ 60 year prorated on wall and frame.
The pool company stated they prefer galvanized steel bottom tracks in this area due to freezing and thawing. (shifting or heaving of the earth) I've seen people in the forum state they don't have any problems with their resin pools in cold climates. Should I be concerned with the resin bottom rail?
Again, I'm really wanting to use a SWCG (looking at the CircuPool Edge 25) to simplify my life. Spent a few years with an Intex pool using liquid chlorine and hated manually adding it, skin feel, worrying about levels when we'd go out of town for a few days, etc. Also the pool store was trying to sway me on the TripleO oxygen type system over SWCG which again from these forums seems to be ludicrous. Still would assume I'd be using liquid chlorine, etc.
Anyway, any advice would be nice to hear from those who know pools better than me.
