Fully trad but considering trying a backpack for some windows: So, do many trads actually do this? If so, what did you get and what do you really need as a basic set up? Where from? Any downside? I rang the WCW and instead of a £200 unit I saw on the web I got the impression I needed to spend £5/600 to get set up. Reluctant to do this as I would rather use a trad pole if it was that much. Cheers for any help.
