I left my digital camera at the house this morning, but I'll go by at lunch and get the pictures.
We also used Oklahoma Wister Flagstone around the pool (in tandem with oval areas of stamped overlay concrete to break up the flagstone look) and the beach entry coping line is flagstone. The interior wall of the beach entry uses flagstone as the tile down to the water line. The coping looks really nice because the builder put a chiseled profile on the exposed flagstone edge.
I checked my contract and the Pebble-Tec cost was not itemized, but I've already contacted my builder to get the cost and whether the transition between the two colors cost extra.
You won't see the coping line in this schematic, but it will give you an idea of our pool until I post the pictures. The large oval areas that don't look like flagstone are the textured, stamped concrete overlay areas.
