Actually, I intend on changing all the canopies. This is what I'd like to see:
For the 600:
For the 500
I haven't really found a new one for the 450 that I like. Both of the above are Canomod canopies and I think they are awesome. I want matching tail blades and I've even found some RJX main blades for the 500 that have some green in them.
Kbdd has a set that is mostly green. One thing is they are wide cord. This will prevent you from folding the blades back all the way. I have had 2 sets and each set on a different frame with the same results.
