Shockwave makes nominally nice 29mm fiberglass cones. I've had mixed luck-they're either near perfect 2-part mold cones (no plaster top coat like the old PR and wildman cones, fiberglass right at the surface), or they're terrible-completely out of round and misshapen. CarVac got that one replaced for free, though. The cones are a little bit on the heavy side but you will never be able to break it.
I don't know that their CF tubing is; I've seen performance rocketry carbon fiber tubing that was wrapped-fabric style and also seen some that was filament-wound style. Either way, for a 29mm MD, it's probably unnecessarily strong. The colored tubing and profusion tubing are identical to the G12 tubing in construction style; they're all filament-wound fiberglass at something like a 60 degree wind angle. Far from ideal, thick-walled tube, totally indestructible. The colored ones have pigment in the epoxy matrix, the profusion ones have powdered graphite to make the tube look like CF and also to add a modicum of strength. I don't know if the profusion tube has enough graphite to inhibit radio and GPS. The G10 tubing is fabric-wrapped fiberglass. It's lighter than the filament-wound tube and almost as strong in lab tests-but it fails more readily in the field. A friend lake staked a rocket that had a blue-tube coupler and a G10 fiberglass tube in front of that, and the blue-tube coupler split the fiberglass tube down the middle and barely got scratched in the process.
You want something light and stiff for this. If you don't want to make your own tube (which is what I'd recommend, all the commercial tubes will have thicker-than-necessary walls), I'd order the plain G12 or Hawk Mountain G12. The Hawk Mountain tubing is a little lighter and a little thinner-walled, and is stiffer (but more brittle). At this size, the brittleness almost certainly won't matter.
Or, get a thin-walled paper tube (for a motor mount), and put 2-3 wraps of carbon fiber around it, wrapped under tension, and you'll be in even better shape.
EDIT: ahahaha CarVac beat me to the punch. You can tell we're both having trouble focusing on homework today. =p
