Upside, we have had two pools. The first one was Tahoe Blue Pebble Tec and our current one is Aqua Blue Pebble Sheen. The Pebble Sheen is smoother and easier on the feet. Keep in mind though that even Pebble Sheen will be rough on the kids feet after they have been in the water for a while. We took it a step further and tiled the surface of our large baja step. It was a little more expensive, but makes a big difference. Good luck,
