I am planning on buying an oval pool 15 x 26 x 54 info-15' X 26' X 54" Quest Yardmore Space Saver Oval Pool

25 Gauge Mystri Gold Unibead Vinyl Liner
Hayward S180T Sand Filter System with a 1.5HP Powerflo Pump (sand not included)

I am however hearing stories about the buttress free not being a good choice.

Any thoughts?
