Strings

[Boltshooter]

It seems that the older excalibur bows were equiped with dacron strings, which give lower velocity than fast flight strings. Do the new bows with molded limb tips come equiped with the "excelerant" strings I've seen mentioned? (Not in the kit, just with the bare bow.) If so, do the excelerant strings give about the same velocity as the fast flight flemish strings?
Sorry if this topic has been adressed before.
