From my research, having floorboards doesn't negatively effect lean angle. It's not great for either, really, but she's not your naked bike. So it's really just a matter of preference with that. I do like the boards (don't have them though) because they suit the chromey aesthetic look of my first edition. It strikes me as odd that, of the two, they'd have 'em on the standard.
Regarding FE vs Standard: you like the standard, get the standard. You may be among the first here with one and, frankly, we're up to our ears in first editions. You'll save a bit of cash and can always modify the paint. If you opt against the floorboards, maybe you could finagle a grand off to swap back to pegs too. OR, maybe you could feign love of the floorboards and try to get the dealership to swap them to the FE; keeping the price where it is?
