I'm not going to cherry pick the classifiers, that really isn't productive. The point of shooting 5-gun in IDPA was to develop my skills while shooting.
For the USPSA GM thing, I'm just going to practice the "skills" of the classifier, which are really just the fundamentals of marksmanship at Warp 8. I want to be a better shooter, so simply gaming my way into it doesn't really help. Ideally, I want to be presented with a classifier that I've never shot before and shoot 95-100% on because I've increased my skills, not because I've cherry picked the easy ones.
Im lucky as well that up here in the PNW I could shoot 4 classifiers a month if I wanted to.
