I'm building #1 and I am intereted in group input on truss rod designs. I'm considering the Siminoff rod vs. fabricating one similair to StewMac's traditional Rod. Not that I have any expertise or credibility on the subject, but for some reason I'm skeptical of the design of Siminoff's arched-L shaped Truss rod system. It seems like alot of the compression at the neck heel is going to come from higher up - closer to the fingerboard - which seems couterproductive to me?
To be fair I have never used or seen this system work, so I'm looking for advice and expert opinions (and maybe a physics lesson) on which system is the most effective to use.
