Nice bike Teal! My current H-D is a '09 FLTR(along with a F800GS, and DR-Z400S for the gravel/dirt). Been riding one Harley or another, for going on 25+ years. I tried the Syn3 in all 3 for a time, and it works fine. Nowadays, oil is at such a high level of performance, that as long as you change it at regular intervals, I don't think it makes a rats ass difference what you run, as long as it meets the manufactures suggested rating. That said, I now run Syn3(or another high quality equivalent) in the crankcase, and Formula+ in the tranny and primary. Mainly because the shifting just feels better with Formula+ over Syn3. JMO. Keep the rubber side down, and enjoy that bike!
