My self bow is 1" wide at the handle with no shelf.
Like Arne said, just shoot and try to do every thing correct.
Learning to tune arrows (spine) has been a challenge for me, but thats my lack of experience , not the bow.
Learn as much as you can about tuning. be carefull, you might get five different answers to the same tuning question!
As far as canting the bow or tilting your head; nock an arrow, Come to full draw in front of a mirror,aiming at your self ( don't let go Ha Ha) you might be surprised to learn what "lined up over the arrow" feels like or looks like.
Good Luck, God bless,
Scott
