Buying a Dolfino above ground pool

Hi my wife and I are thinking of buying one of those above ground pools by dolfino. We are going to go with either the 18ft X4ft or the 15ft by 4ft one.

I was just wondering if there was an advantage to buying the one with the steel frame as apposed to the one with the air ring for the top.

Also does anyone know whether these pools are ones you take down in the winter. We live in Ontario Canada so are winters can be fairly hard.

Thanks
Jason

The pools with the ring on top definitely have to come down in the winter, I believe the steel frame ones should too. I would go with a steel frame pool since you will get a little more depth out of it and they last a bit longer.
