Get lever clamp or Z pole folding type. The twist lock types fail, either getting stuck or slipping.
Alloy pole slightly heavier, but there's a chance you can bend them back if you ever take a big tumble onto top of them and bend them.
Carbon less chance they'll fail in that situation, and lighter, but if they do fail then they're buggered.
I use carbon pole from Aliexpress. About $100.
