C Drives sound like the goods,but at the time in 2015 none seemed to be available .
For my 8,7 SG on smaller days the JC quads (red /yellow) work a treat,huge amount of drive/speed!
For when its big,down the line or for big hollow beachies I have down sized to the Shapers Core lite quads (blue /black),
In comparison obviously smaller,a little bit more upright than the JCs with more flex on the tips.
