Renting a Track Bike: Ninja 400 or EX500?

This will be my 4th track day, but I no longer have a bike and I'd like to rent one since I have an itch to get on the track no matter what. I was wondering what others would recommend since I'm torn here between a Ninja 400 and an EX500I used to have an 04 Honda VFR800 that I tracked, it was fun but heavy, and the riding position was more upright. I was usually in the C group, and always felt my hands go numb from gripping the handlebars too tight (yes I know 'squeeze with your knees' but that only somewhat helps).I'd say I was more conservative wit the VFR on the track and took a more "ride a slow bike fast" approach to it - this is my reasoning for the EX500. I also want to try a more aggressive lean vs. an upright position which favors the Ninja 400.Is the Ninja 400 *that* much faster than the EX500, and would it be a faster bike than my old VFR800? FWIW I've ridden a CBR600 before on the street though never tracked it.What would be recommended? Either way, I'm looking forward to getting on a smaller, lighter bike to see how it feels on a track. via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/bb7wzd/renting_a_track_bike_ninja_400_or_ex500/?utm_source=ifttt
