"My reluctance on CF poles is because I have broken a couple LT4s. Not necessarily the fault of the poles, as I hike in some pretty rugged places. Also they are two piece versus 3 piece, which probably means there is a lot more flex in a longer section. Perhaps the 3 piece are less likely to break because of this. The other thing I do not know is how thick the other CF brands are compared to the LT4s. Obviously the LT4s are much lighter, but they don't have the heavier flint locks. But I suspect the LT4s are a thinner material."
The BD CF poles are much beefier than the LT4's. I have both and would be hard pressed to think of a situation where I could break my BD CF flint lock poles, unless it were deliberate. Thicker material and, as you mentioned, shorter, overlapping pole segments. I would at least take a look at the CF poles before making a final decision, were I you.
