I stopped listening to those pseudo pro-gamers when I got my Spawn when everyone was all over it.
Needless to say, its sensor is picky about pads, has very low perfect speed, high lod, and jitters @ 800 dpi.
Uber crap.
My Sensei is perfect(at least to me): Ultra low lift off, VERY high perfect control and malfunction speed, no skipping, and works great at any DPI, and at every single pad I have(9hd, talent, stealth, dkt, goliathus speed).
Sure, its has a little acceleration, but it's a great all rounder.
