Regarding my Snipe, I'm considering at the moment if I want to make a new set of struts and the fittings that attach them to the bolts in the spars. Or I could just use the struts I have and re-rig the left side to match the right side.

Right at the moment, I feel like removing all the rigging on both sides and starting from scratch. On a two (or more) bay biplane I would assume that you should first entirely rig the first (inboard) bay with all the correct incidences and dihedral and then move on to the next bay.
