RE: Zebra String Stretch
My guess is that for whatever reason they figure the Zebra is a better choice for the average shooter. The average shooter doesn't set up the bow minutely for peep rotation, they use elastic tethers, or nopeep sights. They are, maybe, more likely to prefer a quieter sounding, lighter string.
If you want WC type performance, get a Tiger string with low stretch, low creep material. I mean get it factory installed when you order the bow. What you buy for your next string is up to you.
I don't buy the WC hype, nor do I question that they are great strings. Mathews strings are no spin/twist, when properly installed, no difference there. If they stretch, it is the material. They don't claim the Zebras are low strech, but neither are WCs made out of the "wrong" material, and they leave that choice up to you.
All this WC pre-stretch stuff sounds fishy to me. If you stretch something beneath the elastic limit, it will return, so by the time it is shipped to the customer, and on your bow, what is the difference. If it doesn't return because you stretched it beyond the elastic limit, you damaged it. Creep is different. As far as I know, you can't stretch the creep out of a product, it isn't the same thing as stretch. The difference is like with limbs, they have a certain amount of spring, bending them (analogous to stretch) will not remove the springiness, unless you SNAP bend them beyond the limit. But the relaxation that occurs in a limb that is held in a bend over time, can be related to creep, this can be lengthening along the glueline as the plastic materials adjust to the bend, or the same kind of lengthening within the epoxy limb material itself.
The whole point about super string fiber is that they hardly creep or stretch, so pre-stretching them won't help.
