I can assist you with the cracking of the W4s when I return from a trip I am taking, that isn't a problem. I can't offer guarantees, but I can if and only IF things goes wrong, you can have my Cracked W4s and I will take your BAs to have customs made out of them, since I will be buying a pair of W4Rs when I get back anyway. Hope this lessens the risk for you. My W4 were bought in May 2011.
Yes that would be great, thanks and lets hope i manage to successfully crack them myself with your instruction
