I play both the C10 and the O10 325g, but haven't sampled the O10 mid - too many racquets (including some mids) at home already. I didn't much care for the O10 until after I put a little lead tape on its hoop at 3/9 o'clock, but it absolutely came to life for me once I did. My easy answer is to recommend a test drive with the Super G 10, but I also encourage you to get a pack of 1/4" lead tape in case you want to experiment. It might just make a world of difference.
You could even consider steadying up the hoop of your O10 mid with only a few grams of lead tape, too. If it doesn't work, it's easy enough to just peel it off.
