I remember there was someone in the FS threads offering a $10 pinching service or something and he wouldn't reveal his methods either and was blasted for it. Haven't seen him since really.
I am not a nitro guy so I don't care either way but I do agree that being as transparent as possible is going to help. Especially on the net as there are tons of sucky people out there wanting to take advantage of someone looking for a good deal.
Truly wish you the best!
