This was originally part of our "experimentals" line and wasn't intended for full release. This (like Megaviscerate) was more of an experiment than anything. Feedback was really really strong though. As for how much more effective I just don't know that we can quantify it at this point. I do know those who have ran Ab Ab have been really pleased with the results. People who have lots of experience with OG will end up being the best judges of this in the long run.
