My new pool (Echo Canyon) isn't up yet...but I was extremely impressed with the quality of the pool and the thickness of the steel walls. I'm not sure if you were able to look at a display demo that was up at the store, but..the quality as compared to the other pools my store offered was off the chart! The warranty was non-prorated 60 year which seemed impressive. The top rails were 9" with a resin track. Structurally, it just appeared strong. You may want to email "huskerfan" a member of this board who purchased an Echo Canyon to see how they like it so far. I'm hoping we'll be happy once it's installed.
