I think I am going to go with the Pebble Plus. However I am going to go view a couple of pools with it first. Here is a link to the PP sample (with optional glass and abalone) next to the PS sample that we liked (they look even more alike when they are wet) and a bonus pic of the waterline tile and step marker tile we want. Regarding the few hundred extra, we are already past our budget and I would rather just downgrade to plain plaster than pay an extra penny at this point! Lol.
