[1] Compared to previous Uukha limbs, the beginning of the draw has the same easy feel as the Curve profile.

[2] The end of the draw is as progressively smooth as in the Xcurve profile.

[3] Stored energy remains high, and speed is improved thanks to the limb’s overall design and construction.


Faster limbs improve accuracy especially in windy conditions, the lower trajectory means less time in the air, less wind drift, better sight marks and easier unmarked estimations at the longer distances.


Smoothness brings a pleasant comfort to your draw. This helps when shooting many arrows by helping you maintain proper technique, as if you were using a lower poundage bow.

Smoothness is a characteristic of the limbs’ profile and their draw force curve (DFC) at your draw length. Less slope means more smoothness.

The S-Curve’s smoothness is equivalent to that of the Xcurve, as the increase in poundage during the last inch of your draw is only about 3.5%.

The Curve’s smoothness is similar to that of smooth laminate limbs, with a 5% increase in poundage during the last inch of the draw.

Limbs which show a 6% or more increase in poundage for the last inch of draw are usually not considered to be smooth limbs.


Every archer seeks a stability which allows consistent arrow grouping. Stability comes from the limbs’ torsional stiffness. This acts at two levels: first, if your limbs resist torsion, it will be very difficult to apply torque to the riser, and your bow will remain in line; second, when the arrow accelerates, nock travel will be straigther resulting in better grouping.
