Rodgeek blanks are made by St Croix, and from all I've heard, are very nice blanks. It sounds to me like appearance is a priority with you (as it is with me-if you are going to do a custom rod, and you can get really good blanks in about any color you want, you might as well make it look as good as it performs,) I have done matte black rods, and while they look good if done right, I really prefer glossy blanks for appearance. A little detail that does make a difference, glossy finishes don't show minor screwups in applying the wrap finish as much as matte finish blanks do.
Rainshadow Immortals are a little pricey, but are wonderful performing and very classy looking with their gloss titanium chrome finish, a finish that goes with just about any color wrap.
I presume you're considering 4 piece. I will build nothing else in fly rods now. I don't believe there is a discernible action difference between 2 and 4, and the 4's travel so much better.
A new product that really makes sense on a fly rod is the Winn Grip. Take a look at them and if there is a color that works, you may want to give them a try. Better grip and comfort than any other material, IMHO.
