Top / bottom limb location
When the bow is in shooting position, the poundage markings must be upside up.
Profit or loss of bow sight scale mark
Does a profit on bow sight scale mark correspond to a speed profit when we compare two limbs pairs ?
Not necessarily: the bow sight scale mark depends primarily on the archer morphology and the position of the nock point compared to the riser with the maximum draw length.
According to the way in which the two limbs top and bottom work, the height of this nock locator can vary.
None of the traditional adjustments (Brace height, tiller) being made at the maximum draw length, there is no reason that the nock point height is the same one with the maximum draw length.
To do a comparative speed test, we know two methods:
Compare the bow sight scale mark at 70m and at 10m: the smaller the variation the higher the speed.
When the bow is correctly set up, the noise is very short and dampened (a bit like a silent gun) . Limbs stop at once with very few oscillations.
If it's not the case:
Check tiller screws are between medium and max setting (the more the better).
Check brace height is what we advice see "Tuning"
Use a string made of BCY 8125 or better astroflight (I don't mean other brands don't work but those 2 ones work well).
Last and very important, use a good stab with a good damper and a mass at the end.
Limb saver has never been for us a solution.
It is an integral part of the structure, so it is very strong. Moreover, it is very compact and elliptic for a better air penetration, and a low inertia.
The shape is studied to preserve your string serving: we do not change a string after a endurance test of 30,000 cycles at 35" draw length.
They only fit on Uukha limbs.
