For a start - lightweight/performance-driven modern parts on a noodly, lugged steel frame? The frame will negate most of the performance gains of the components. Descending on wobbly steel with deep section wheels, sounds like a nightmare. I know no-one gives a toss about that here, but...
I don't think a custom modern fillet brazed steel frame is comparable to the old skinny "performance" frame of the past.
