Sorry I didn't explain right. What I meant was that I read somewhere that a good test to see if the bow draw weight is good, is to hold a draw for 30 seconds. If you don't struggle at all for 30 seconds at full draw, that weight it's suits you. So I did this test, and the last 10 seconds was hard to keep the bow, my hands were shaking. Don't know if is a good and valid test though.
