I will say, I did at first rip the pdf from elsewhere to read it in full but honestly it's such a good system, I paid extra so I can actually own the pdfs and honestly I might give more because I truly think this is great and I am thrilled to know new systems are being made at this quality. i hope you dont get hung up on the first part but TL:DR this is really worth the buy and i want you/others to know that.
