It depends on which system you go with David. If you choose a stand-alone AFS AoA for instance, you'll be adding upper and lower ports out near the wing tip, and use pitot as-is. Both Dynon and Garmin now use a dedicated pitot tube that has a third line for AoA - and for those, you'll need a specific pitot tube with a custom mount - very easy to do however.
I was under the impression that since AFS and Dynon teamed up, the AFS AoA could also use the various Dynon pitot's, or do the 2 small ports drilled near wing tip. Maybe I am misreading Ironflights post, or the info from AFS/Dynon.
