A question: we're moving to Phoenix and will build a pool in the backyard. What is the required pool depth needed to execute a flip turn? The builder says 3' 6" is fine; one web site I found refers to this depth, anothers implies 4 feet are needed. What do you think? Also -- the pool length is 40 feet -- not much by Olympic standards -- but do you think this is fine if you just plan to do a bunch of flip turns? (and have the depth to do them in!). Thanks :)
