crazynate,
I don't want to sound the least bit disrespectful or condescending, but I honestly don't think you have a grasp of basic human physiology.
You can't draw a bow, hold a bow at full draw, or pull thru your release without tension on the rhomboid muscles--it simply is NOT possible. That's what's called back tension.
When you say, "I don't believe in back tension", to many of us, you'd just as well say, "I don't believe in the moon." You may not pay attention to the moon, but it's there just the same.
