Dave, If you did get the X-outs, you could use those boards for other purposes, such as process development, residue characterization, baking / solderability tests, etc. Many companies benefit from having a few extra boards around to play with, especially when it comes time to troubleshoot a new process. You might also keep some of the X-outs on file as a representative of that particular lot or shipment.
