For me, no sloping and nothing other than steel with lugs. And, like my 911s, old school and stripped to the bare basics. Here is my daily driver, beer getter and all around short distance transportation. It's a custom framed, used japanese keirin professional circuit ride. They still build them like this in Japan. No two alike, all custom made, all lugged, all strong as hell, all built by one man for one man in a tiny shop and none sold to mass foreign market. Sort of like Japanese sword making. To buy one, you figure out your size, go here and wait for your perfect used custom frame to appear after some pro decided to get something new built. All are built to perfection since it takes years to become an NJS approved builder. Just one failure during a race will end up with that builder losing his approved status. They are ridiculously cheap considering the decades old craftsmanship which one has to search for even in Italy today.
