I normally shoot a MH Takedown 3 under and I don't know how it's tillered but I keep the brace height at about 7" and the nockheight at 1/2" or 5/8" and it shoots great and arrows fly great.  Just got a Montana LB and the nockheight is about 1/8" and the arrows fly better shooting split.  Is the Montana tillered a certain way?  How can I tell what my two bows are tillered for?  Can I compensate for tillering by moving the nock or switching styles?  Please educate me.  I prefer 3 under BTW.
Thanks,
Mike

Measure from the string (braced) to the upper and lower fade outs.  The very end of the riser wood where it disappears into the limbs.  If the upper measurement is larger than the lower by an eighth to a quarter inch, the bow is tillered for split finger.  If the measurement is the same it is for three under.  You can compensate for split tillering to shoot three under by raising your nocking point height -- you just have to play with it, all bows are a little different.

I can shoot most of my split finger bows 3 under with about a 5/8" nock set height.  1/8" seems low, but if it is shooting ok split it likely needs a little more 3 under.  Just play with it a little.

That makes sense.  My MH takedown is about twenty years old and I'll bet it was tillered for split-fingers and it wasn't until I got the nock height up to 5/8" that it started to really shoot great for me (at least as good as I can shoot it)  Make sense to you?

The Montana is a great bow, its tillered for split fingers. I shoot mine 3 under and my arrows fly like darts! Sounds to me yours is to low, I would raise it a tiny bit at a time, I've found raising/lowering the nock point the slightest will affect the arrow flight bigtime!

Tillering is very much over-stated regarding shooting styles.  For years, guys and gals shot barebow by stringwalking with so-called split finger tillered bows.  There may be enth' degrees of difference, but it won't amount to much.
