Only tried them once, as part of a store's sample of "bigger" condoms - they were a little bigger than a Magnum from what I remember, but not as much as the XL. I personally found them too tight to "perform" in, so can't give any help over the lube situation.
For girth, Durex XXL still seems the best; for length, Magnum XLs. Though anything over 7" thick or 10" long you need to hope TheyFit.com releases their new line this year - bulk-buying from them solved all my problems.
