Thanks, Matt.
One quick question
Sometimes you will see a "spring back" effect and you will have to over tension the line setup, tension the tramp then release the line and as the frame settles in, it will end up more square.
Which setup were you suggesting might have to be overtensioned? The blocks squaring the hulls or the rig on the sidebars? I am guessing you meant the hulls, just allowing for some drift in them after you release the blocks.

...and of course, this winter I had finally bought a tramp tensioner
