RE: holdin steady
This usually indicates a fit/form issue.IMO,both draw length and poundage fit into this category.
This is the main reason I do not like a bent bow arm,much more difficult FOR ME to get good bone to bone contact and stay relaxed during the aiming process.
Another thing is most good shooters really aren't trying to get the pin to stop moving,that is almost impossible to achieve,they key is to LET the pin float on the intended AREA while executing back tension,you will be amazed at how the arrow will hit the center of that area more often than not.
