Peter V thanks, that's great info, and the rest of you. I, stupid sod, have bought really tiny rings. But I like spinny. The big one won't be too far off the smaller, going from what Peter says. I am really crap at climbing. Looks like I'm going to be OK with what I have planned if I fettle it carefully. Might try to build this today as it's bloody pissing down out there at the mo.
