Thanks, Alan and Doug. The reason I'm asking is that I have a Fibraplex pole set for my 2-pole (wedge shape) Big Sky Tent and it suffers dramatically relative to aluminum poles with respect to snow loading.
I also have them for an Integral Designs eVENT MK1 Lite, also a wedge design, and they are fine, the difference between the CF pole set and the Al pole set is not as dramatic.
The differences are probably related to structure and how the poles are secured: clips in the BSP tent and interior with velcro in the ID tent.
But clips don't tell the whole story. In my hoop tent (an MSR Zoid), the CF poles are excellent, and the difference in performance relative to the Al poles is even less.
So, in short, when you are considering an upgrade to a CF pole set, consider the loss of performance relative to deflection (very high winds, snow loading), and recognize that the loss of performance will have a great deal to do with the tent's structure.
I did break a CF pole in a Hilleberg Akto, and I've broken a set in an ID MK1XL, both from excessive snow loading. The Akto, I left in my backyard for a week of storms, and the MK1XL, was in the real world on Froze-to-Death Plateau (basecamp for Granite Peak, MT) in the winter during a heavy snowfall. We couldn't dig fast enough.
