Hi Rabb - welcome. I'm a newbie to the forum too (although strangely it feels like I've been here all my life already!)!
Those are some quite serious bikes you've mentioned considering how much things will have changed since you were last on a bike. I've not long passed my test, however I have been riding for the last 10 years fairly constantly, and on some bigger bikes too (where legal to do do of course!)
I went for the slightly older ZX6R (636) as I too wanted a sports bike, but this is the most forgiving of them all, but it retains great performance. Possibly a good consideration for a year or so, and then move up to a Gixxer 750? My dream bike has always been the '98 R1. I'm giving myself 2 years on the ninja, then if I'm comfortable, 2 years on a 750 then get the R1 I always wanted.
