Hello, i have had a Vanguard Nivelo Bk before which worked well and was extremely light and very compact at 12 inches folded, and worked well on the X-Pro1, we have now switched to a Giottos Memoire 50 (max cap 3KG) and and is 33cm collapsed. 128cm max extended, with twin spirit levels and a arca style QR plate. with a hook to hang my bag from on the centre post.
Very nice tripod and was very cheap at only £23.00, not sure if they are still available but are currently on offer at Currys electrical, if this helps anyone.
