Shot my 62" longbow today, without stellar results, so i went in, grabbed a 70"er, went back out and beat the crap out of my block target.
It may be a psychological thing, but for me the longer the better.
To me a longbow was designed to be long and anything under 66" is to short to accomplish the forgiving nature of the original longbow design.
Seems a lot of the forgiving nature of a long, longbow, is sacrificed by going to short.
Looking for your thoughts on the long and short of it?
