I have the same problem, (well the mtb I hardly use and the retro bike is there because its pretty) - my commuting bike is my main bike for everything practically, hence my heart ruling my wallet. However commuting is 95% of my miles (except in the summer where I may go out in the evenings) so I incorrectly surmised that the OP's main mileage is commuting like mine.Problem is, for most of us, the commuter isn't just the commuter. Mine's my tourer & gravel path bike. For a long while, the SCR2 was my road bike, errand bike, commuting bike...because it was my only bike.
