RE: , Help with new bow
No, you never, ever want so many twists in a bow string that it starts to kink up.
No telling what's going on. Might be the bowyer made a mistake and made you a 60" bow instead of a 62". It might be that he doesn't list his bow lengths by AMO standards. It could very well be a 62" bow, if you use a cloth tape and measure the length, being sure to follow the limb's contours. That is the generally accepted way of measuring a recurve's acutal length. A bow with a lot of curvature in the limbs could have just as limb length as another recurve with a lot less curvature, but still appear shorter when strung and compared side by side.
Unless you've got an extra long draw length, 2" in bow length isn't likely to be a killer anyway. You've just got to fit the bow with a string length it likes. Try an AMO 60" string and see how it works. You might have to get a string custom made that'd be 61" AMO.
When you find out what the actual string length is, make sure you record it. That way you can order by actual string length instead of AMO length. Or, maybe, get into making your own.
