It was asked earlier flo 2.0 or 3.0? 1 vote here for 3.0. The 2nd tab cleans up the wake which is an ultimately better wave. Add another $2 to your payment and have the best wave possible and never have to 2nd guess yourself. I ordered mine with 2.0 because it was brand new and not proven yet when I ordered mine. Wish I ordered it now.
