I think the problem when handling a Hill bow is to have a natural bow arm, any forced extension will result in a more felt shot. Try a natural bow arm. Raise your arm up to point at something in your line of sight, you don't hyper extend your arm.
As for Hill style bows, If you can find a Shultz Old Favorite, buy it. These bows tend to have some string follow due to the fact they do not have any glass backing. The string follow helps soften then shot. Another bow is a Shrew Hill, with it's tiny tips and wedge grip, there is hardly any felt shock.
