Would you recomend thin material or thick

Depends on the weight of the material. Some teams like to use cereal box or cardstock blades. Others go for balsa blades. Both, I think, have proven to be effective, though it is up to you to experiment with to see which one fits your preferences better.

The rules say "The CD must fit on the mount found in a standard CD player.
Modification of the CD is not allowed (except to affix the blades via tape, glue, etc.)." I cannot think of anything else other than tape or glue to fix the blades to CD. Are there any other ways to attach the blades to the CD without modifying the CD. Are plastic screws allowed (that would require holes in CD)?

The rule is written like that to permit tape or glue, not prohibit it, so I'd suggest sticking with your initial instinct.

It's probably also possible to build a slotted blade that has a friction hold on the cd (akin to a paper clip) but, tape or glue should give you a light and durable hold.

A slotted blade won't work, at least for this year. If I'm understanding you correct, you're implying that the blade goes on the thin edge of the CD, correct? Since the rules prohibit any part of the blade on the rear side of the CD this year, a slotted blade would be in violation.

Good point - that's rule 3.f. Don't do the slotted blade idea. Glue or tape works fine.

Technically there are also ultra-small screws (you'd have to use nylon, not metal ones) you could use to mount to the CD, as long as no part of the screw protrudes from the back surface (either via trying to thread the hole in the CD or via counter-sinking from the back side).

Wouldn't that modify the CD?

Yeah, but its allowed. The rules say no modification except to attach the blades. This modification would be to attach the blades.

I would have to ask, for what reason would you want to use screws when tape works perfectly well? If you are considering making an adjustable blade system using a screw then I would recommend simplification of the design.
