Spectra or dyneema wishbones were made for Shark-fin and pinned shafts to provide a quiet and stealthy shot and eliminate the risk of cuts to fingers.  With the HammerHead Helix system with dyneema wishbones a spearo can easily change-out their bands without the use of tools.  In addition, speargun muzzles without any slots or cuts in them are stronger and more streamline than those with band slots.
