about twenty five years ago I was first introduced to three under as an alternative to the method I had used since a young boy...one over two under...
I was never a "gap shooter", and never used a sight...always just instinctive , both eyes open and focusing on my target.
I had a friend who had his bow set up for three under, and he asked me to try it out...he said just use your tab, but put all the fingers underneath...it was a long bow similar to the one I shot, so I tried...
Immediately I was aware of how my view was different. Also how even though I never really looked at the arrow, somehow it was right there.
then he explained to me how the tiller was different so the fistmele(brace) was closer to my eyes line of sight...and that the bow was balanced closer to even because the rest was right on top of my hand.possibly because the tillering ws even rather than reducing the pull of the upper limb??
Long story a bit shorter...I havent switched back since. I really appreciated the difference when hunting especially...
shooting bows cut to center, and shooting with the bow at a cant seem to be a natural for this set up. Tiller is even or 1/16" less on the lower limb, closer to even the lower the shelf is. The paradox of the arrow since the bow is canted does seem a bit less , and the arrow is nocked at square or 1/16" above (depending on tiller) on bows that are tillered at 1/8" the nock seems best at 1/4 above...one thing I do notice well is arrow flight...
...my accuracy became more consistent, and my hunting shots seemed much more managed..maybe sub concientusly the arrow is being looked at??I cant say yes or no...
I can say that having my draw fingers even with the throat of the bows grip must be the reason it works so well for me.Possibly it is more a natural move for Hand Eye coordination??
I am curious if any others have some ideas about this...all the best...ted
