I know there are hundreds of pool liner posts (it is proving to be the most difficult choice) but this is specific to size of pool. I am having a smaller pool installed, 14x32. I live in Virginia beach and it does get HOT in the summer. The pool gets morning sun and then filtered from about 8-11, and full afternoon sun until its starts slowly getting shaded by the house at about 5. Do you think a liner like Latham's gray mosaic or Merlin's gold coast will keep the pool too warm? Should I stick with something lighter like Merlin's Island granite?
