Babolat Pure Storm GT series?

I have a semi western forehand and a one handed backhand. I love to serve and volley, play at the net but I also like to play on the baseline. I want to purchase a Babolat Pure storm racket but I was wondering which one would suit me the best. Which one (Babolat Pure Storm Gt, Babolat Pure Storm Tour GT, Babolat Pure Storm Tour+ GT) is better for me?
I've been playing tennis for 10+ years

Simple answer: demo all three and see which you like best.

The differences between those frames will be pretty subtle. It's something you'd really have to feel to know which you prefer.
