First off - congratulations to authors and publisher for a great work done on this book.

My copy came with a very nice profile on separate sheet - what a great idea! However - is there a way to obtain a specific profile? I got 'Black 10' WNr 500618, but would much rather have 'Yellow 11' WNr 4006xx (p.272). Is it possible to exchange it? I'd even consider buying it - I think making these available for sale would be neat.

Thanks,
Pawel
