And I see that you, like me, run your front tire saver "backwards". That is, pointing toward the incoming tire, which I did for a specific reason I've mentioned before so won't go into here, but, I've since placed mine under the fork crown. I agree, they're handy and, I think, prevent flats. An important consideration for me, what with tubulars being such a pain to fix.
