They're insanely fun, but damn, you have to pump for days. I'm about to have a 3 1/2 footer, but given the choice (and funds) I'd much rather own a 5 or 6 footer. We already have vert at the concrete park, and our private spot has a 5 foot capsule that waterfalls into an 8 foot bowl, so a 5 or 6 would be perfect for home...
