I am ordering a cab (2x12) from Avatar Speakers and i cannot decide if i should go with two Celestion Vintage 30's or one and a Celestion G12T-75. I play alot of classic hard rock, and old school metal. Some bands include AC/DC GNR METALLICA DIO OZZY SABBATH ZEPPELIN SKID ROW RATT etc. Now originally i was going to get the 2 V30'S but i notice that GC sells a set for hard rock and metal with one V30 and the other G12T75 and that they supposedly complameint each other well. What is your opinion? Thank you.

Heres the link to the set and aswell to the cab:
