but, the Flemish Twist is slightly heaver than the Continious loop.
- I have made several 2 color continous loop crossbow strings, Actually as
described 2 continous loops served together. How many extra strands if any
would depend on the poundage of the crossbow.

- I have made Flemish crosbow strings and they work just dandy. Of
course, like all Flemish strings they stretch at first and need to be
twisted to compensate, but once stretched out they work just as well as
a continuous loop (made those too). The conpensation for the crossbow
versus a hand bow is that I served the end loops. I believe there is a
great deal more stress on the end loops of a crossbow string than a hand
bow string, thus the serving. I also double served the center/contact
area as this tends to take a great deal of stress both from contact with
the bolt end and the prod/guide rail. And, yes, they were pretty
because they were two toned. Look good, shoot good.

- Crossbow strings do take a lot of abuse at the loops. In part because
this is where the shock is greatest at the end of the power stroke. But
also in part because the string is bent around a very small radius.
Another small radius is the sharp bend at the release nut when spanned.
So these are the two places I have seen crossbow strings fail.
