Should I buy GH2 for Xbox 360?

I've been thinking... and remembering GH2

Now with the les paul controller I think I could EASILY tear through the whole @$#%ing game on expert no problem

The only things I couldn't do in GH2 were things that I can do in GH3 with alot of ease

Guitar solos dont mean shit to me... I never even star power for solos anymore

I'm sure the shorter time window isn't that big of a deal since I pretty much still hit notes right about when I'm supposed to anyway

I beat GH2 on expert on PS2 with the crappy old controller... now they got that great DLC pack and I got a les paul with smaller and closer together buttons I figure it would be alot easier right?

Has anyone tried playing GH2 on Xbox 360 with the les paul?
