Standard RRG trad rack for most people is doubles of fingers through fists. If you're a BD owner this would be .3 to 4. Then add a set of nuts and micro-cams. This will get you up 70% of the routes you'll want to do.

For your rack, I'd suggest the following;

Add two BD .3's. Add one ea of BD .4-3. Add two #4's. Forget the Hexes. Forget the tri-cams. Add a single set of micro cams. I'm impartial to Master Cams vs. C3s at the Red, but I LOVE aliens, so I'd buy those if you can find them.

So here is a caveat: If you can find aliens, I'd say buy those through yellow (black, blue, green, yellow), and forget about the BD .3s. That will be tough though. It will be much easier to buy the BD .3 and then go with either C3s or TCUs or Master Cams that are smaller. Any of these will work in the Red, and everyone has their opinion which is the best.

The money you save by NOT buying hexes and tricams will be spent on a 3rd #1 2, & 3 BD Camalot. I call this the girlfriend rack. With 3 BDs in the hand range, you can go climbing with your girlfriend (who has no rack of her own), and get up 85% of the RRG trad lines.

To critique jrathfon: you have more gear than is needed for a solo ascent of the Nose on El Cap. I'm starting to think you have stock in BD and are trying to earn some dividends.
