is the tub punctured or is it still useable? if it’s still useable you have a spare tub right there. add to that the dura ace 10 speed cassette, and the 24H zipp rear hub and that’s the total value of your shimano wheel right there. not to mention the zipp skewer. Now all you have to do is ask zipp to sell you a flashpoint rear rim and you can recycle the spokes too. Not bad for a brand new race wheel.
