Have been jumping my 140sq.f. for over two years now, in all kind of temp's (winter like summer) from Bjorli, Norway (up to -20'C at 10000f) to Perris Valley and Quincy, US (hot like h#"$ below 15000f).
It's like a Porche 911, safe, smoth and nice - and a heck of a ride if YOU like to have a rodeo.
My one and only choice - for lifetime!
