I was having this discussion with JPF the other day in his place of work.
In all my experience playing live, ive played through countless cabs, from custom 2x12s to Harley Benton 4x12's to Mesa Oversize cabs.
My favourite has actually always been the marshall 1960A with G12T-75's, and my least favourite cabs are fully loaded with V30's. I don't know why, its like you say, they just seem hard work.
Although now i use a mix of V30 and T-75, i still prefer that to the fully loaded V30 4x12.
I just got some Classic Lead 80's, and mixed them with my V30's, and I was playing today, A/B'ing with my V30+T-75 cab, and i prefer my V30 + T-75 cab to the one with the V30s and CL80s.
I might try the CL80 + T75 mix tomorrow, failing that, i might my classic leads and go back to what i had in the first place.
anyway. yeah, It seems like a bunch of somebodys must dig them. I don't mind them, just not by themselves.
