Restrung the last few crosses, pulling tension at 52lbs CP. There wasn't quite enough length, so I skipped the last cross before the tie off.

Far from ideal, but its going to have to do until my replacement sets arrive. Will be interesting to see whether its playable or whether it plays like a dog (I suspect that there's too much tension loss or uneven tension in the stringbed now).

With a pre-production sample, we gave Zyex MonoGut the “poly tug” when tightening the knot during tie-off and broke the string, as did a couple of our playtesters.
Very relevant comments from the USRA. When I originally got it, it felt like a poly out of the packet, so I'm assumed it was like poly for stringing purposes when in reality its softer and more susceptible (than poly) to breakage if you're not careful. No breakage when I tied off on the occasion in the above picture. You just need to be a bit more gentle as it doesn't like cack handedness. The string also seems to weaken in any area along its length where it twists or bends onto itself alot eg. a knot.

I experimented with the spare piece of ZX that was left over from not stringing the last cross. If you bend the string 180 degrees back on itself and deliberately kink it under pressure (I squeezed the bend using some pliers) and then flex the bend backwards and forwards repeatedly using your fingers (and we're talking trying to deliberately damage and break the string), it just disintegates like liquorice at the point of the bend. It breaks very easily when you force it to bend backwards and forwards over extreme bending angles.

Doing exactly the same thing with a spare piece of RazorCode (Tecnifibre's new baby) and no matter how many times you deliberately kink it, crush the 180 degree bend with pliers, or wrench it backwards and forwards at the point of the bend, or wrench it with pliers, it just doesn't seem to want to break. Very tough string, though not sure how that translates to arm comfort - stiff probably (RazorCode playtest coming up but that's another story).

ZX is clearly alot softer and less durable than a typical poly. It doesn't resist brutal attempts to break it well. Then again, the trade off is that its alot more comfortable than a poly, and I don't see how during play the string would be subjected to repeated extreme angle bends backwards and forwards.
