KW,

The Easton Tuning Guide addresses tiller by adjusting the nocking point.

Your whisker biscuit will work best with the limb bolts set at an even tiller, which can be set real close by simply backing both limb bolts out from max an equal amount,and nocking the correct spine arrow at 90degrees to the bowstring.

The windage for the whisker biscuit for a right handed shooter, will often be about 1/8" to the outside of the centerline of the bow, because the bowstring when its released, moves a little bit to the left at the release.

The windage should be set to the point where the bow shoots its narrowest groups. Cam leans and cableguard tensions as well as draw weight are not going to be the same on all bows, so setting a bow up with a lazer is just a starting point not the end of the game.

If the bow is set at an even tiller, and the cams are in time, and you are shooting the correct spine arrow for the bow, and you have determined the correct windage setting for the rest, you should be shooting the arrow level from the bow.

If the arrow doesn't hit level, but hits nock high, you can adjust the tiller to correct by adding tiller to the lower limb, (tighten the lower limb bolt).

If the arrow doesn't hit level but hits nock low, you can correct the tiller by adding tiller to the upper limb, (tighten the upper limb bolt). Untill the arrow hits the bale level.

You can also subtract tiller from each limb to steer the nock lower or higher, while keeping the arrow nocked at 90degrees to the bowstring.

If you want to have the arrow hit with the nock lower either add tiller to the lower limb, or subtract it from the upper limb.

If you want to have the arrow hit with the nock higher either add tiller to the upper limb, or subtract it from the lower limb.

Even tiller bows shoot quieter because the limbs cancel each other out. The recoil at the shot is even and they don't kick up or down at the shot.

Properly set up your bow will shoot many differently spined arrows accurately at ten yards, but only the correct spine arrows for your bow will still hit the same vertical line at 10-20-30-40-50yards. Doing a walk-back tune with too light a spine arrow will show a hook to the left. Too heavy a spine will shoot to the right.

Most of the bows that I have set up with a whisker biscuit you could simply line up the centerline of the bowstring with the nocked arrow and the front sightpin and they would all line up together. Some bows had cam leans that needed the rest moved a bit to the left in order to shoot the best.

Good luck hunting! >>>------------>
