Very nice bow, how did you put the reflex in the limbs? I've never had much luck heat-bending hickory.
Sometimes when you do a full draw pic, if you are canting the bow even slightly it'll make the top limb look a little stiffer. That or even a different grip can change the look of the tiller a bit. Its pretty darned close if you ask me, should hold up fine at that length and poundage.
