Well, that's WAY too conservative. The plate height is 8'-1" 
yielding a l/d
ratio of
64.8. I also won't get many "brownie points" by telling my 
client he can't
have his
party wall. Yes, the reason for the staggered studs is for 
sound. Even
though the
resilient channels yields a satisfactory STC rating, it really 
isn't that
great. The client
wants better performance. Need to do better.

Thanks anyway,
Bill Allen

Bill,
Typically, the studs are braced in the weak direction with stud 
bridging (consider conventional construction) that is generally 
used as a fire-break as well as blocking to control H/t. Section 
2326.11.8 of the 94 UBC requires bridging in stud walls were the 
height-to-least-width ratio exceeds 50, which is in most cases. 
I have yet to see a wall (other than cripple walls) which are 
not bridged at least mid-span of the stud.
Considering this, I would think that your wall would be just 
fine unless you are stacking enough loads to cause the studs to 
buckle out-of-plane (in the studs strong axis).
