Get a used racer, cheaper and already for the track days. Either will be great and unless you are a star you won't know the difference. But a 600 for the track is an excellent idea I'm sure you'll love. I ride my sv650 but have ridden a yzf1000r too.

Repeal helmet laws, they only protect people we most likely don't need in the gene pool any way!
I think the RR looks way cooler then the R6, but beauty is in the eye of the beholder. If you guys put an R6, GSX-R, ninja 6R and a cbrRR all next to each other with matching paint. The CBR 600RR is the only one that stands out. I can tell the ninja because of its ugly front fascia... but all the 600's look almost the same to me with exception of the CBR which is a good thing.
