No recommendations, i only have the £100 10ft Asda one for the last 3yrs, great fun, but my old knees have taken a battering this weekend.
Got a tent to go over the top recently, so we're gonna camp out in it when the weather warms up a bit.
8ft to 16ft is one hell of a jump in size, double the diameter is 4x the area, sounds huuuge
Enjoy
