...What characteristics make a good longbow? ...[/QB]
Forgiveness.
I have a longer draw so want a bow that only adds 3lbs or less at the end of my draw. I like a 64 inch longbow but some 62 inch I have shot are equal in smoothness but they are fewer- that special one that comes along out of every several made.
I like a finger indent grip but made my own to get it (the bowyer left the grip unformed).
I prefer mildly R/D bows but that may change with my Ossabaw, a pronounced R/D design by Marty Thompson.
I've shot a lot of different longbows but wonder how many of them shot or felt poorly because they were not tuned to my draw or some other little detail. Come to think of it the best shooting bows almost always were already set up right by the bowyers themselves.
As a way to compare, a bow I can stack the arrows with right away is a good bow for me- I'm not a great shot yet, but know when a bow works well with my form and style. Whether shelf detail or shelf cut or what ever it is I know when a bow has it for me.
A lot of it becomes psychological after that IMO.
