Choosing Aluminum Coping/liner track for concrete pool

[jumpinj]

Originally, we just figured we would install the basic aluminum bullnose coping system for the liner track on our concrete block pool, but now I'd rather find one with a flatter front. Where would I find these? I'm only finding the round and the one that slants inward? We don't want to go the paver or concrete forms route. TIA

This is a VERY unusual pool so you may not get many answers. Here is a bump to get more eyes on it. Good luck!
