Hi! We are new to the forum and need advice. Can anyone compare the metal frame AG pools to the ring AG pools? Has anyone owned both? We have owned a 16' x 42" Quick-Set ring pool for 6 years and loved it! We set it up each year on the lawn (no pad or prep whatsoever) and take it down and store it each winter. Now they have the metal frame pools which look about the same to me? They seem to be more expensive on average, so are they better - or just newer? I do like that they have the filter attached to the side of the pool rather then having it sit on the ground. I also like that there is no plastic ring to clean under and around (lots of dirt, bugs, ect. get trapped under there in ours). We have four kids ranging from 13 down to 1 year, and a wide variety of swimming abilities. The little ones do a lot of hanging on the ring. Is the metal frame sturdy enough to support this (or soft enough for the little guys)? Does the surface need to be completely level for the metal frame? It doesn't seem as flexible as the ring. We put ours on a slope so there is a "deep end" - will this work for a metal frame? Or should we stick to the ring? Give me pros and cons for both please! Thanks so much!
