Paul,
The SBD was a 10 strand also and had wooly whispers on it and yes the serving is slick on his strings. I normally serve with Halo also but on this particular string I actually used an orange monofilament. Silly,but I never gave it a thought that maybe that may have had something to do with it.
I am not done with the SBD strings yet,I know it is just a matter of tweaking it somewhere. And maybe that will be adding another nockpoint. But for now Dan's string is staying on,it is really shooting well.
Good Shooting,
Craig
