7 string guitar truss rod question

    My brother is building a set neck 7 string guitar and he has a question about the truss rod situation. He's going with a bubinga neck with either a rosewood or ebony fingerboard, and the scale length for this guitar is going to be either 26 and 3/16" (I think) or 27".

    He's wondering what truss rod setup he should use. He's considering either a Warmoth double expanding truss rod, with or without steel rods, a Stewmac hotrod rod (I think that's also double expanding), or two truss rods. He thought bubinga was a stiffer neck wood, and to be honest I have no idea about that, or what truss rod option would be best in light of the stiffness uncertainty, so any help would be greatly appreciated. Thanks!

    Thanks! Great advice. I will tell him that. Any idea what depth the Warmoth rod requires? I am a huge fan of those and that's what I have been pushing him to.

    I haven't used one so I can't say for sure, but glancing at them, they look like 1/2" deep rods to me, given the stationary and mobile rods appear to be of the same stock.
