I just received a UQP from 2QZQ that will work on my RR and WBBB. The design is right on and the workmanship is impecable. They also responded to my request within 30 minutes of my initial request (late on a Sat night) and later called me to confirm the details of some custom work.
They also offered to make a bag for my spreader bars and their design and execution exceded my expectations.
Additionally, they sewed flaps on the tarp of one of my hammock friends. Again, the work was impressive. It even had velcro to seal the tarp.
I highly recommend 2QZQ for all your hammock accessories and mods. They have excellent customer service and do fantastic work!
