I had a 1978 3 ply kit, 24 BD 14 and 15 mt, 20 ft, and when you did that rock beat with 8ths on the Ft you ruled,huge sound all around.
Using single ply heads I still felt best using a 5 b stick,with emps or pins I had to use 2 b's ,I couldn't really dig in using anything lighter,when playing rock.
