On the MFX Bone Collector ($105), thick walls make the shafts super durable, while microdiameter increases overall penetration and minimizes wind drift. In addition, the thick walls add weight, which enhances kinetic energy and, thus, penetration. These shafts come with HIT (Hidden Insert Technology), meaning points rest directly on the shaft walls rather than on the rims of inserts, a feature that ensures precise head alignment and accuracy.
Bone Collectors are available with ViBrake X-nocks, which use Sims NAVCOM IV to reduce vibration and decrease recovery time, resulting in tighter arrow groups. Having tested these arrows, I can attest to their superior accuracy and penetration. Straightness tolerance is +/- .003", weight tolerance +/- 2.0 grains. The MFX Bone Collector comes in four spine sizes: 300 (10.7 gpi), 340 (9.5 gpi), 400 (9.0 gpi), and 500 (8.1 gpi).
