I've posted a few times and received great help, thanks! I've also tried to answer a few questions for each one that I've asked...
Thought you all might like to see my pool. Completed October 2015 by Cody Pools in Austin TX. Overall quite happy with the whole process - as much as anyone can be happy with major construction in the backyard! Major details are in my signature.
My pool is unusual as it's on quite a slope as you can see. The top of the front of the pool is at grade or a little above it, the bottom of the back of the pool is at grade, more or less. At the steepest point it's about a 1:3 slope (1 foot of drop for every 3 feet of horizontal distance) or about a 32 degree angle. It's technically an in-ground pool, although as you can imagine only about half of it is actually in the ground!
Here is the result
