We know that there are several good solo pyramid type shelters from the cottage manufacturers. Many of these require a center pole that is 48" in length. I don't normally use any trekking poles, so I normally purchase a segmented carbon fiber center pole for that correct length.
For short poles, like 30-40", a carbon fiber diameter of slightly less than 0.3" works. For very tall poles, like 54-60", a carbon fiber diameter of 0.45" or more will work. However, for a length like 48", it would work best for some diameter between 0.3 and 0.45". Obviously, the bigger the diameter, the more they weigh. OTOH, the smaller the diameter, the more likely that I could snap one if the shelter were hit by a bad wind or if it had been erected at a cocked angle.
I've had a carbon fiber pole crunched before, but only due to crunching by an airport baggage handler while inside a duffle bag.
So, for a pole length of 48", what do we think about the optimum pole diameter? I know that there are not very many choices on the market.
