Guys this is my first post in awhile, but I've read on the forum for a long time.
Some of you are looking at functional bows, which is where I can contribute a bit. I haven't seen this discussed, so if it has been I apologize.
I haven't shot since college, (not on a team, they just had the facilities). Anyway, a need for a right handed or left handed bow is not necessarily based on whether you are right or left handed- but instead based on EYE DOMINANCE. Everyone has two images that merge, but one overpowers the other. I, for instance, am cross dominant so I shot a left handed bow, despite being right handed.
To test eye dominance-
1) Find a friend or a mirror.
2) Touch your thumbs and index fingers together, and make a diamond shape with the gaps between your hands.
3) Stand about 15 feet from the friend or mirror, Point the diamond from #2 down at the floor, then quickly raise your hands up and aim at your own head (mirror) or the friend's head with the diamond gap you made.
4)You or your friend will only be able to see your dominant eye. That indicates the kind of bow, right or left handed, to get.
5) For most people it will match your handedness, for a select few it will not. If you end up cross dominant but don't want to shoot that way, then you will want to close the dominant eye when shooting and shoot based on your handedness.
6) When shooting, the dominant eye is furthest from the target, and in line with the bow string at draw. Unless you've chosen to close it, of course- then use the other.
Youtube has a lot about archery technique and good olympic recurve matches. Right now I believe Brady Ellison (An American) is ranked World # 1 as we close in on the London games.
Just a thought, but Renner may have discovered he was cross dominant in between Thor and The Avengers, which is why he shot with different handedness between the two movies. ( I know he shot CGI arrows, but I suspect he did train for the role, but maybe not for the cameo?)
Anyway, hope this helps...Thanks
