I am flying the prototype of the Pro Series Extra 34% with a 3W 106B2 on 3W Cannisters, and my all up weight dry is 25.5lbs. The only difference to the production models is that the hatch is actually fiberglass and the canopy is not as long. So I would say that the weight range of the production models should be 24-28lbs. Depending how you gear it out.
