The Blurs are "Rounder" than the Cyclone and will give more options in drilling. One flaw of the Cyclones is, when you drill them weak, they're very long and lazy. Drill them strong and they're long and jumpy with that high RG core. The Blur's are strong on the medium and under stuff but all give a slightly earlier rounder motion. The Blur Pearl and the Cyclone, same drilling, you may the Blur as a little "grabbier" in the dry boards where the Cyclone is going to push then flip more.
