I am also concerned with my rig and truly only feel confident in it after I do the inspection and tune it myself. I purchased a Loos rig tension gage (model PT3-M) so I could determine the tenstion of all shrouds and stays. The tension gage can be used while under sail, so it will give me real time rig tensions.
The instructions that came with the gage say you should tension the rig at the dock (several tension values are given depending on your rig). Then you take the boat for a sail in a stiff wind and basically tune the rig so that the lee shrouds do not go slack (dynamic tune?). As long as there is no slop in your rig including mast pumping, and the tensions are close to what is considered typical, rig should be considered well tuned (assuming rake and mast bend are acceptable).
