>> What is the durability of these poles in comparison to the Life Link Guide Ultra Lite?
Jonathan -- we really shouldn't compare these, because the two poles are in completely different categories.
The LLGUL is a multi-section pole so it will suffer (not unique to this pole, but applicable to any multi-section pole) from failures at the joints and adjustment mechanisms, and won't be as stiff.
Let's talk about "Durability" as a characteristic unique to the shaft, then.
A stiffer shaft can be more and less durable than a less stiff shaft.
Stiff shafts don't bend as much, so if you do get the tip stuck in something, they are less forgiving and more prone to catastrophic failure.
But, because stiff shafts don't bend as much, you are less likely to damage a shaft simply by leveraging your body weight on it, as might occur if you're going downhill, plant your pole, lose your balance, and end up transferring the entire weight of your body and pack into the pole. Pole shafts that bend can bend to the point of failure.
The latter is a rare occurrence, and one that I never worry about. I'm not carrying 250 lb of body and pack weight either, so maybe it's a more critical issue for somebody else.
However, breaking a pole at a tip because the tip gets stuck is not as rare. This was the single biggest motivation for me to change shafts from the old Stix to the new Stix, and why I haven't had good success with thin poles like the the GG ones. The new Stix aren't immune to tip breakage, but the tips are more durable than either the GG or old Stix.
Now, back to the Guide Ultralight. Tip durability on the lower carbon shafts of Life-Link poles is awesome. One of the best on the market, in my opinion. The disadvantage is that you do pay a significant weight penalty for it - the LL carbon poles (even the fixed length ones at 12 oz/pr) are starting to get up in to the realm of "not ultralight", and this does affect your swing cadence significantly.
