Quick Advice for Vanguard

I was thinking of making a Vanguard with the Reaction Aspect and was wondering if there is any way to get any more bonuses to Dirty Trick then just the +4 from the free Improved Combat Maneuver(Dirty Trick)?

The Hindering weapon fusion gives you a circumstance bonus, so it should still stack. But you will have to use a melee weapon to gain the fusion. Hope this helps. :)
