Blue 32!

I got to see and use a 11.5mm prototype of this rope at the GOTC Rendezvous this year in Michigan.
  • Very tight, very tough and very slick cover.
  • Very dense in hand.
  • Feels much heavier than the specs listed on Wesspur's website.
  • Knot-ability is OK but not great.
  • Runs great in the Petzl Zig Zag.
  • Probably not the best for DdRT/MRS regardless of what Yale is advertising.
  • The rope had more stretch / bounce than I was expecting and what Yale is promoting.
  • Current pricing is darn silly and way too high.
Bottom line there are much better ropes out there for much less. Might be a OK rope to catch on sale but not at the current pricing.
Well, thanks. Nearly pulled the trigger just now...but resisted. The price makes no sense.
 
What's up with the 5,000 lb breaking strength? Isn't 5,400 the Z133 minimum? Or have things changed in the last few years?
 
OK here is my take on it. All the ropes we climb on are fairly static bar none..tend slack properly and make sure you always have taught lines. This is not rock climbing on dynamic ropes. I really do hate bouncy ropes. I have not climbed MRS since 2012. Unless off a crane..that is not climbing though.
I had a bouncy kernmaster save my ass once when my tip broke. I still climb with some of the most static lines..
last wesspur order I wanted to get a few screamers, best of both worlds but they aren’t carrying them anymore….

You know what, you are right. I just opened my Z to verify.

"8.2.4 Arborist climbing lines used for moving rope systems shall have a minimum diameter of 1/2 inch (12.7 mm) and be constructed from a synthetic fiber, with a minimum breaking strength of 5,400 pounds (24.02 kilonewtons [kN]) without terminations when new. Maximum working elongation shall not exceed 7 percent at a load of 540 pounds (2.402 kN). Arborist climbing lines shall be identified by the manufacturer as suitable for tree climbing.

EXCEPTION
In arboricultural operations not subject to regulations that supersede Z133, a line of not less than 7/16 inch (11 mm) diameter may be used, provided the employer can demonstrate it does not create a safety hazard for the arborist and the arborist has been instructed in its use. The line selected shall meet or exceed the standards for arborist climbing lines and shall be identified by the manufacturer as suitable for tree climbing."
 
I have often wondered what kind of hazard they worry a slimmer line would create? What are the special instructions for slimmer ropes that the climber is supposed to recieve? I am especially keen to know, since I taught myself how to climb on an 11mm rope...

Agreed…. What is this special training?
Even half inch ropes are actually 12mm or so.

All I can think of is to teach a new climber about the relationship of prusik diameter to host rope diameter, but frankly, I have run several 10mm prusiks on 11mm ropes without issue... I wonder if there is a way to ask ANSI what that means?

Love 10mm AP on 11mm static lines. What a flier.
