Does leading up a racquet have the same effect of heavier stock?

[Thor]

if ill lead up a racket,will it play exactly as if it came stock with the same weight(and balance)?
i mean,since you add lead the racquet should have more twist in the frame,power issued etc.after all,lead concentrates the weight in specific points,while stock heavy racquets have it distributed evenly all over the frame.
any thoughts on this?

oops ... this sounds like another SW issue ... ;)

more like weight distribution which is concentrated in stripes in the inner hoop VS spread allover,and whether adding weight by applying something which is not the racquet gets the same effect.
