Can't be done.

I shot  split for 2 years with a recurve. I changed to 3 under to bring my arrow closer to my right eye, thinking this would really improve my consistency. I worked on it for a month and went to a 3d tournament and shot 2 points higher than I shot previously.

I would pick what feels best and stick with it. I don't believe either is superior. For me it did change my point of view a lot when shooting, which took a lot of relearning. I won't ever change again.

Can't be done!

No! Don't! You Can't shoot a recurve 3-UNDER!!!!  And I hear that, in certain states  you can't shoot 3 under at all and if you do the Sheriff of Nottingham will throw you in the Dungeon and not even Robin Hood and his band of merry men can free you!!!    

Funny this topic comes up, I myself tried 3-under yesterday after shooting with another local trad guy who shoots that way and I have to say I felt like I was a bit more accurate, got the fat lip to prove it (gotta figure out the right anchor for me).  I did notice that I felt like I was developing a blister on my middle nice to see you-finger though.  I was using a split tab with a spacer.  Reckon I'll try to yank the spacer or try the glove.  At first I felt like "gotta shoot split!" 3-under seems like I would be using the arrow to align it and that wouldn't be true instinctive but then again, accuracy IS the name of the game so I guess I should just get over my mentals     Dang that wall is HARD!!!!

Good convo me brudders!

Um...not to get into the "true instinctive" argument here but coming from a pitcher who has the elbow to prove it even throwing a baseball is a learned behavior.  

As for three under...for me, from day one it was always easier and more accurate.  Plus I NEVER worry about pinching the arrow or pushing on the nock with my fingers during my draw.

I still anchor with my index finger in the corner of my lip so the arrow is what...3/4 of an inch closer to my eye?

Go with what works best for you.

Went to a 3-D today because I like the challenge of looking for my arrows on the wrong side of the target.  I shot 3-under for the majority of 28 targets and was pretty satisfied with my shooting.  Seems that I might be a nock pincher when it comes to split finger.  OK That's me.  Only you can control your destiny, grasshoppah.  You will decide what works best for you, I say give it a try and see what YOU think.

By the way, my wife kicked my arse on the shoot.  I am not ashamed.
