I'd seen this lock before, I can see that from a security pt of view, it is most likely much more secure than any coil lock, but for touring a coil lock is always going to be more convenient because one can quickly lock your bike to odd shaped objects-a tree, a picnic bench, whatever-and for me, thats much more important than pure strenght or a lock not being able to be cut.

I know its always a crap shoot with thefts, risks are always there, but usually one doesnt leave their bike alone when on tour that much....(touch wood)
Im also leery of having a key for a lock with me on a trip, but thats just me.
