I made the switch 2 years ago. I don't think you will find a professional archer that will tell you NOT to shoot left handed if you are left eye dominant. I asked lots of folks and this is why I say it. I talked to several folks at the pro shops around here and sent e-mail's in to Dave Holt, Norb Mullaney, and Len Cardinale(sp) asking this question and got 2 outa 3 responses from these guys. My question ended up in Bowhunter magazine and everyone said SWITCH! Oh,...I also talked to a couple gun shops and was told that I would be hard pressed to find a top skeet shooter that doesn't shoot off the dominant eye. I REALLY did my homework on this one because it was a big decision,...AND I was buying Matthews ($$$$) and wanted to be certain!!
This was after 15 years of shooting right handed and I shot pretty well by most standards. My experience with switching started shaky the first few sessions, and I initially actually had some anxiety because it felt so strange that I was thinking my body was outa whack or something and it wouldn't work. I had to change my anchor point from under my chin to the back part of my jaw.
It will be a win win for your friend!:
1. An open stance will feel more natural.
2. He will be shooting from his dominant eye which is just plain correct!
3. He will also have a added advantage in that since he is left eye dominant and right handed,...he will be using his dominant right hand(usually strongest arm)as the bow arm.....AND that is a plus.
Get him started correctly and he won't have to make the switch if he really gets into this sport and is searching for every little thing to improve his game!!
