My first longbows were both made by John Schulz, if they had much hand shock, I did not notice. The first ASL I shot was a Pearson, that one kicked pretty hard. Then the Howatt Martin longbows showed up at a shoot. M10 or something like that, a mule with a string on it.
I must disagree with Kirk a bit on what has more hand shock and less speed to a degree, I have a string follow that is not slow nor does it have hand shock with a B50 string on it. Some bows have a lot of limb mass and energy that does not get into the arrow at the end of the cast. I rebuilt a walking stick that started life as a Howard Hill Mountain Man model. Before reworking it from tip to tip, I shot it, gravel gouges in the string grooves be damned. I shot it with a straight arm and as long a draw as I could muster. Holy crap, my ears flapped on the side of my head and just for second there I went blind. It turned out to be a very pretty and nice shooter and 5 pounds lighter when I was done, with a padded BCY string on it. Those Jerry Hill bows with action wood lams and about of 2" of back set had a hardy kick as well. Once I shot a heavy one and opened my hand while taking a long hold at a PAA target, I always shot with an open hand with target bows, plus wrist sling, that bow tried to beat the arrow to the target. With a normal longbow draw and grip, sure it had some thump, but it was pretty quick and accurate. I think we make too much about hand shock and it seems that those that make the most out of it are shooting with stiff arm form that does not work well with ASLs and straight grips, they would be better off shooting recurves that matched their form and shooting style.
