I've played with both but bought the Avalanche. The Cyclone is a neat knife, but it doesn't seem comparable to me to the avalanche. The avalanche has some of the best G10 scales, a beefy construction, it's a good EDC size and it's quite affordable at only 80ish online. I've been very impressed with mine. Also, I don't have to be careful with the AO at all...it's much less likely to open than my Bump or mini mojo....the force has to be applied at the correct angle. I've learned to like thumbstud AO. It isn't as good as flipper AO, but I always felt that if I have a flipper, AO was useless anyway...
