snowboarding is a ruthless bidnis and brands will give freebies to ensure retained custom;
when i bought burton binders, i was provided with several base plates discs to fit them to more than just burton boards
when my missus bought rome binders, she e-mailed rome to say they wouldn't fit her burton board, rome sent a new, second set of discs.
you should not pay for the ineffectuality of a product. they will.
now send that e-mail!
