Fused is a bit longer and more angular, Parallax blends the lane more and is more continuous, the Fused had more of a hook/set motion. I think the Nuclear Cell is a much closer comparison to the Fused, but the Nuke is 3ish boards stronger though. If you don't mind a stronger Fused, go Nuke, if you don't mind a smoother Fused, go Parallax.
Luke, where does this fall in comparison to the Hyper Cell Fused. Have gone through 3 of the HCF's and love them. Looking for something that might fall in that slot.
