It has charts that I made for Fittings, Braided line, Scale Hardware. I personally use on RB Motion A/N Fittings on my builds. Robert is a great guy to do business with and I have even had him machine some custom pieces for me as well. As for Braided line my personal opinion is that Pro Tech is the best in the business and Charlie is a great guy to talk with and do business with. Bob from Scale Hardware is another great guy I get all of my bolts from. Take a look at the link
