Jinx,

You have never discussed what type of pool finish you plan to put in the pool. Plaster, aggregate....???? I start construction on my pool next week. 36 x 22 IG gunite w/ white plaster. I have a neighbor that has the SunStone select aggregate finish (Darker blue/green finish). Not sure of the true name (emerald/pearl/etc.). Anyways, my wife and I could not find an aggregate light enough for our liking. Long story short, our neighbor has the Color Logics by Hayward (3 in pool, 1 in spa). they light up his pool just fine. Even with the darker aggregate, the light does penetrate and is very vibrant. We also have chosen the Color Logic Lights. I have not seen the Jazz Lights in action, so I can't give comparison. However, my wife and I were thoroughly impressed with the 5 or 6 pools (All Color Logic Lights) we looked at before choosing our builder. Good Luck. Send pics after you decide and finish your build. I will do the same for comparison.
