The way i see it is why have all that length waving about in front like a snooker Q when you can have the same length barrel stuck out only half that far, got to make less prone to muzzle drift, also the weight is in close making it more stable, im talking off hand shooting here, for bench rest and the like the traditional layout would probably be more effective, imo.
Tho i think 2 grand is 2 much.
