On a recent order with Eric at RSM I had some ribs lazer cut. I was asked if I wanted jig holes, since I use the Adjust-o-Jig I said yes 5/32nd holes just like your kits. Eric mentioned problems with the rib trailing edge some times not being totally straight and if you need to pull a jig wire during construction you would have alignment and support problems with the Adjust-o-Jig. So along with my ribs came a solution to the problem. Must be nice to have a lazer cutter at your finger tips  $$$$. I should have no problems making a perfectly straight wing.
