We use Advanced rules and most of the alternate rules (Variable damage, a slightly tweaked glancing blow, alternate munitions, forced withdrawal, formation movement variable movement modifiers, etc). We also have a few house rules in place, for example we treat aerospace as a separate phase that occurs after all ground movement is completed, and players must move their units in legs of movement, rather than trying to measure out the ENTIRE movement at once (A few Atlai ended up moving 10" due to shady measurements around corners). One thing we're testing out now is actually placing every unit on a 2" circular base to ease edge to edge measurements. Prior to that we measured everything from center to center to avoid the disparity between flat and corner on the bases, and that not everyone's base was the standard 1.25" hex.
Our current PV per force is at 480 points, and we use formations, force abilities, and individual SPA's (At a ratio of 1 per 4 non-infantry/support vehicle). Fair warning on using all three, you end up with very tactically complex games. We have a round 3 beer rule in place, that everyone buys a beer for their opponent on round 3, as that's when the shenanigans tend to drop and feelings get hurt.
