Yeah, looking like the top, even though it is against what Insight states. Maintenance will do the skin mapping. If we get a chance, thunderstorms are forecast next couple of days, would like to tow the airplane in a circle to make sure the WX remains stationary as my display is slaved to the aircraft heading.
I had a WX-10 in my "commute-mobile." I flew this PA-22/20 back and forth from South Texas to Hobby for my airline flying. The commute up was always at 1 pm, and back, 1 am. Those commute times would light up the display. 1200+ commutes taught me the value of a lightning strike system.
