I thought I read somewhere that some bowyers used-to, or still do, make some adjustment to something - perhaps tiller - to make their bows shoot arrows high, and make the archer think he had a super-fast bow. Is that ringing any bells? The reason I ask is that, as a g...g...g...gap shooter, with one of my bows I am having to aim waaaaaaay down low underneath the target to get the arrow to hit it. This is at ten metres. I don't like it, as mostly all I have to do, with my combination of arrow length and physiology, is put the tip on or just under at that range. But not with this one bow. A metaphorical penny for your thoughts, then, gents? An instinctive shooter wouldn't have this problem, perhaps.
