Exped and Snow Peak make a set as well.
I'm looking for something light to use in place of trekking poles on a trekking pole tent. So something around 45-50 inches in length, adjustable would be nice. Something that on occasion can go to 6 or 7ft for use as a larger tarp pole instead of just being relegated to trekking pole replacement for tents.
