I also have both.
I drilled the G-force label (pin slightly above finger line and right of ring, and MB about 3/4" left of thumb). I left it in OOB condition. It revs hard in the mids and is STRONG!
I first drilled my Carbide+ the same way. It was nowhere near as strong. I plugged the C+ and redrilled it CG axis. It is better, but still nowhere near as strong (in oil) as the G-force. The Carbide+ is better suited for medium with carry down (for me). On a heavy shot, the C+ will skate a bit, but the G-force is sweet.
