The beer-can shim has never worked for me, except when the seatpost was already a pretty close match. If you have to make up a big gap, it fails pretty quickly.
I might try the aluminum can thing, its very close in thickness. So if that does not work ill have to get shims.
Thanks for the comments guys, here is another photo from todays ride to the cherry blossoms in dc. Best way to view them is by bike, so much traffic around here.
