Gilky, thanks for that idea, may take a bit of practise training the pinky but your right I can see that benefiting for lots of new style playing for me.
I was thinking of Sisters but I think that maybe a bit too hard for me at this stage, but it is a very cool instrumental and I do plan on tackling it one day, it's also over 4 mins too so that's a lot to learn, and Ballerina is my first
Steve Vai track I've attempted, even though I've been into his music since 92, but I played way too much Metallica and such in the 90's, still fun though).
I recently just finished learning Midnight by satriani and that took a couple of months

and tears in the rain again a small tune took me a good month to learn (mind you that had several chords i'd never seen before so my fingers had to learn the positions throughout constant repetition).
