Tail Tidy or short rear Fender (Mudguard)

[Papa Weeley_imp]

I think the fender eliminator works best with the stock '13 seat, or a cafe-style aftermarket seat (like CB4ME's above), where there's a sloped rear profile to the seat that blends into the "manx-ed" rear end.
For chunkier seats like the '14 DLX, or Tiro, or K&H High seats, I think the shorty fender looks better, so the rear end isn't so abruptly stubby looking.
A bit subjective, I know, but that's my opinion.
