I love steel over alum any day and I haven't ridden carbon yet. My ole Peugeot is steel and it is such a sweet ride on the road. I now have a vintage Trek Alum and it was like riding a car with bad shocks! LOLOL I'm getting used to it but I sure do love steel.
As a foot note: I would take a Luna anyday coz A) she lives/works in Santa Fe which is all of 55 miles from me and B) she's a ....well a she! LOL......as for the tires, I can't help ya there much since all 4 of my bikes have different size tires so I just don't think about it.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
