I'm not a fan of people chopping into frames, especially good clean straight frames. I see FAR too many "custom" or "chopper" or "bobber" projects that are for sale when the person all gung-ho to do "whatever [they] want to [their] bike" discovers that building to some idealized look results in an unrideably uncomfortable garage queen of a bike.
