I've done No Illusion, which was quite enjoyable, with one stellar 5.9 crack(ish) pitch - a rarity for limestone in the Rockies.
Great climb. Good rock, high friction slabs. Crux's protected by good bolts.
I have climbed both the Illusions of Greatness and No Illusion. Both were great climbs. The rock is surprisingly solid and protection standard for the rockies.
