Gotta have center serving to shoot, so in the absence of any advice (no big deal - nobody seems to know much about this Hammerhead String, or stock center serving material), just decided to bite it and go with .022 diamondback.

Watched a few center-serving vids where folks put a strand of serving material under bcy #62xs .021 serving string to make it thicker. So I'm making an educated guess that it will work.

I would call martin and see what size they use. If i were to guess i would say its .019. I prefer halo serving to all the others i have tried plus if you get the white serving it goes pretty transparent which i think looks pretty cool.
