Hi Peter -- I have a set of Weds, and I believe those can be used to make a set of wheels using BBS barrels. The advantage of this, to your buyer, would be that have a lot of flexibility in making the exact wheel they want. I know Weds are a "two piece" wheel, but as I understand it they welded the barrels into a single unit in order to address potential leaking issues. I believe with a good adhesive/sealer this problem can be avoided, so I would think a set of four of those would be fairly valuable.
