In a fantasy world it would be a Bill Mize built Pan/Shovel chopper, el Forasteros style, W/a VL springer, 4 speed, etc.
But in reality, and considering my wallet, probably a shovel chopper in a wishbone frame with a sportster frontend. I'd like an affordable trad chopper for under $5k. When the time is right it will materialize.
Until then I'll enjoy riding my CB750 and wrenching on my BSA.
