They should. Imp. Trip gives a +4 untyped bonus to trips, removes the AoO, and lets you get a free hit after tripping. The Trip ability lets you make a free trip attempt after hitting without an AoO, the only part that overlaps anyways.<br/><br/>Also, I'm pretty sure we can spread out beyond 30ft. while Hasted. The '30ft apart' restriction only appears in the Target line of the spell, not the Range or effects. We just have to be within the 30ft. burst when it's cast.
