I went with a dynon heated pitot. Fitting the mast was fairly straight-forward by following their instructions. I did have to file a tiny bit at the rear end to help fit the pitot better, but otherwise there were no issues. I had to think ahead when riveting the lower skin & pitot in place so as to not paint myself into a corner, but it all went together OK.
RV-9, Empennage and Wings about done, Fuselage started.
