Pretty significant increase in speed, penetration and efficiency compared to the Han I. To be fair my Han I dates back to 2012 and so I wonder if use has caused it to weaken over the years a bit. On the other hand, Justin always said those scores would be about right for the bow as his Ming-4s from around that time scored similar to my Han I.
Of course the designs differ. The Yuan has a lot less meat on it compared to the Han I. The siyahs are far more aerodynamic in shape and mass compared to my Han I's boxy rectangular static tips. I wonder if Mariner has done some redesign to the Han I by any chance?
But still the designs really do differ between the two so much its almost as if a different bowyer's mind is at play here whereas with some bowyers you can tell its the same guy applying similar principles over and over to different models. Both the Ming and Han I I shot were 'chunky' to say the least going back to 2012. And the Han II seemed to follow suite. So I was surprised at how the Yuan was refined more in certain areas to an almost gracile like mass but still not quite as refined to as what say Lukas would conjure.
Nonetheless, a huge improvement compared to those earlier days and models with long static tips. Its a much more efficient bow but with some features that I prefer over even say Lukas', particularly with the grip section being designed with a more appropriate mass and shape (Lukas sometimes has a habit of shaving too much off here in this area, makes it hard to get a good grasp) which was something I always appreciated even from the makers earlier days with the Han I. Its almost perfect construction save for the bubbles on the upper limb. Was a bit surprised to see this considering how flawless my Han I was in this regard but it seems like the Chinese makers all want to make things faster nowadays. 3 months as opposed to 6 when I got my Han...actually I think I got this closer to two. Practically lightening speed in the 'bows to order' world.
