3under/ more weight

[owlbait]

I just got a bow back from reinishing and the weight is much higher then I've been shooting lately. Now that I am trying/switching to 3under I seem better able to handle the extra weight. Does this make sense? I also notice I don't have the bow in my arrow that I did before . Yeah!

You might not drawing as far as you were when using split fingers thus a little lighter weight.

Thanks Bill.

owlbait,
i tried three under for the first time today and found the opposite. i felt weeker in my draw three under. but it did seem to tighten my groupings. and when i went back to split i was shoot way high...

If you anchor higher with three under, which is what most do when they switch from split finger, it reduces your mechanical advantage and it should be slightly more difficult to draw the bow.  On the other hand, if you anchor lower than you did with split finger, you would increase your mechanical advantage or drawing arm alignment and should be able to draw a little more weight.  In short, a higher anchor point usually leads to a higher drawing arm elbow, which reduces the amount of weight one can draw, and vice versa.
