RE: Retracts Air vs Manual
Rookie, I don't know the weight off hand, and my only remaining set is presently in the hands of the manufacturer. I should be getting them back (Along with a few of the new sets) very soon.
Seeing as how you are in Prior Lake, once I get them back I'll let you know the next time I head to the cities and maybe we can get together for a first-hand demo. (My step-daughter lives in Plymouth, so I go to the cities about once a month of so)
