Thanks guys, that is what I was looking for, some feedback from people who have actually built necks.
I should clarify the "USACG" remark. The bashing was done by some forum members, not USACG itself. The remarks (I can't locate the thread now), but some of the comments were along the lines of reducing the sustain of the neck and rattles etc. They are all generally pretty knowledgeable, but I don't think they had ever actually built a neck. So, I was looking for some other input.
Trying to create a template or jig to due the curved channel on my first project just seems like I would be asking for trouble. Thanks again.
