Neil, of all the Oakley-owned stores I've been to in FL, the one in Downtown Disney has been the one with the best staff, followed by the Tampa O-Store. You guys seem to have a grip on things.
But, I tried on the new bombs at a Miami O-Store today (the SoBe one is now listed on the Oakley Website, so I might have to trek out to the beach this week), and they fit great. Might have to buy some New Zeros. But I asked if they could get the nosepiece by itself and got a NO. Same from CS, who didn't know what I was talking about, and couldn't find it in the computer.
