I have several shelters that I could use them for, but primarily an 8×10 tarp. I have a Gatewood Cape and an MSR Missing Link as well. If I am hiking I have rekking poes 100% of the time, but on the bike I could use the trekking poles, but it seems to be a waste to haul 16oz of poles with any UL shelter. The Gatewood uses a 45″ pole, so I would probably aim there.
I have made a nesting 45″ pole from sections of carbon golf club shafts that isn’t too bad, but I thought I would get the state of the art opinions here since I haven’t really needed dedicated poles and didn’t pay much attention to current products. I’m probably going to go with ready-made aluminum poles for lower cost and ease of purchase.
Good job on your DIY poles!
