I'd have to say Robin is my most exciting new guitarist. Since we've seen him more than the others in the new line-up.
I'll admit, that when I saw this line-up for the fisrt time in Rio 2001, I was kinda disappointed and uncertain, especially in regards to Finck and Buckethead. I was like wtf is Axl doing. But that was my immaturity. I changed my point of view when I saw them in Vegas(12.29) for New Years. Everyone blew me away and I was convinced. Buckethead was always a mystery to me. Not a bad thing nor good thing. But mystery does lean more to an curious side which is good for me.
For Tobias (really liked him), Stinson, Fortus, and Brain, I've always been excited about their additions to this band.
