I researched most of the higher end rods when putting my last build plan together, Lentz, Oliver, Manly, Carillo, etc. Frankly they are all high end rods with great reputations, I can't say I heard of any real inherent problems with any of them. I doubt you would go wrong choosing any one of the lot but I ended up going with a custom Scat Lightweight 4.125 crank and Carillo rods (426 SB build). Turned out very nice, the rods were a very nice piece.
