Welcome!
A hornbow? That would be interesting. what kind? pics? Don't twist it... (I twisted my magyar hornbow :\)
Korean hornbows are crazy to maintain.. good luck, if it is one
60lbs sounds quite heavy for learning, I just bought a 20lbs segye bow for tuning my form. I plan to get a 60lbs or more (70lbs?) Korean bow when I feel that my form is actually good and I can hit the 145m target with some frequency with the 41-45lbs. Though my horn bow is already 60lbs..
if you're strong and already have good general form, 60lbs might be fine though ![tongue](http://www.koreanarchery.org/punbb/img/smilies/tongue.png)
However, this light bow stuff is more common in modern western archery teaching (Gao Ying text said ~40lbs, no reason to go lower, but we go lower), but I did it because my accuracy really sucks and I'm sick of it, and I notice it is difficult to rotate my bow arm properly with a not-very-light bow, I hunch my bow shoulder, and my release is not as clean as I'd like. Even with these faults, I was told to just do pulling exercises with a 41lbs bow.. breathing in, then out after releasing (or un-opening the bow - never dry firing)
Though I guess one never stops learning? :\ I guess for "maintaining" good form, a heavy bow is good.
Korean bows are fast. a western recurve with wood arrows at 20lbs is good enough for 18 meters, so a 20lbs Korean bow with light carbon arrows is more than fast enough..
