XBOX 360 Rock Band + GH:WT Question?

Do you reckon I should buy GH:WT band bundle + game



Then buy Rock Band 1 + 2



Would the instruments work and would they be betterXBOX 360 Rock Band + GH:WT Question?
The rockband instruments look better, and the rockband 2 game + Band in a box set you can get for 拢100, whereas guitar hero: WT is 拢150 for the game and band set.



So you could get rockband 1,2, and bandset with the GH:WT game for around the same price as just GH:WT bandset. Oh and they are all compatable with each other
