One other thought... . A guy named Tom Price developed the harness that many use but his real fame was a couple of National Championships and a World Championship win back about 2000. He used Tx200s and would sit the foreend on his gloved fist on his knee. So he used his gloved fist to raise the rifle but it freefloated on the foreend. He shot higherer scores than 90% of the Open Pcp those years.
