Unfortunately I haven't had the 2016 on course for at least 3 years. I'd say I hit the 21 Pro farther (and perhaps consistently higher), but my swing is probably not the same as it was back then and they have different shafts in them (Kuro Kage vs MMT). I love the size/footprint of the 2016 and the 21 Pro, especially compared to the standard 21 and the 19. Probably not helpful really but I'll try my best to answer any other questions you have.That would be fun. From your on course experience how are they different to you?
