Why do you need bi-wire?
Are you planning to bi-amp?
If you make your speaker bi-wire and not going to biamp, than it's a perfect example of going from point A back to point A so that 'job is done, but progress none'. Moreover there's a draw-back with jeopardising resale value of your cable after surgery.
If it's just not to use jumpers than the game isn't worth time and effort seriously.
