I was wondering if anyone had feedback on what style of extruded (pink) foam works better under the pool. I would imagine that the tongue and groove would hide the seems better than the straight edge sheets. Obviously I would still have the seems taped for the tongue and groove install, but I just wanted to see some real world feedback on the tongue and groove sheets. I think I'm going to purchase 3/4" Foamular 250 tongue and groove sheets.
