Some of them do have a bigger thump than others with a B50 string, to be bluntly honest. Some of the hand shock will depend on how you hold the bow and some on even how you release the string. A padded fast flight can take some of it away on a bow that has more kick. If hand shock is a major concern, a mild R/D will make you happier. To be again bluntly honest, I shoot them exactly the same, I enjoy the extra lean and mean bows like the Millers, Timberline and Schulz bows, but pound for pound my Robertson longbows put out a slightly quicker arrow than even the Schulz and are just as accurate for me.
