If true then you are making cables for pennies that are better than the ones I bought for thousands. If true you would quit your job as they would sell like hotcakes. I would be first in line to replace mine with yours. In fact you would be nuts not to send me a set, just so I would tell everyone how great they are and you really could quit your day job.

Now I can hardly wait for the DM, to find out which ones of your marvels you want to send first. The suspense is palpable.
