I have one at the (Cypres) service center. Rigger told me 6-8 weeks.
Seems like it would be best to time your required maintenance during your drop zones down time.
Lot of drop zones that would be winter. Eloy, Arizona, summer!
I visited Skydive Monterey (California) during the hot Eloy summer.
I could not even feel the parachute opening at Monterey!
I have two Wings containers, a W-22 from 2000, and a W-14 from 2013.
Both have a Sabre 190 main and PD 176 reserve.
I had the first one sent back to get the BOOST system added.
The W-22 is not tight at all for the parachutes in it.
The W-14 seems tight for the main, but I haven't jumped that much lately, so it is still a new main.
I highly recommend the magnetic riser covers.
Wings are beautiful and comfortable.
Left side is new(er) Wings rig, 2013, with the magnetic riser covers. Right side is old Wings rig, 2000, with tuck tabs.
I can't tell the difference in operation, they both look OK as well. Not sure if it is worth the extra money.
