UQP for bridge hammocks?

Hello HFmembers and lurkers!
Need some feedback from the masses on a UQP for bridge hammocks. We are looking at making one for bridge hammocks. Here's a few questions we have:
How long and wide should it be?
Will one size fit all bridges?
Is an end shock cord adjustment device necessary? What about a side shock cord adjuster?(Currently have them for gathered end hammocks)
Will loops sewn on each corner suffice to attach at the spreader bars?

If anyone is currently using one of our UQP's on a bridge, how well does it work?
Thanks for the any feedback. :)
