So another option to ponder (firm feel)

Robert your right SPC looks like it would be quick and easy to install and have lined up. not sure all those bolts look as strong as I would like?
but on the other had QA1 looks a little stouter and you would only have to go through the big set up once.

Course the Firm fell may be the stoutest may be important at 130



any more thoughts and real life results?
