Got a chance to try the Silvy yesterday, and I agree with Gee that it rotates less mid/exit than the N2 does. It seemed to me to have more initial steering and is very comparable to the LTC-R. Should be a great option outdoors or for those who like the LTC feel on carpet tracks.
I will most likely stick with the N2 for carpet racing, and hope to try the N3 soon enough.
