Here is a suggestion you can play with: Add a wah you like the general sound of, then go to the wah controller settings (highlight wah block>EDIT>wah control>ENTER>tab to Modify). Play with the Mid, End, and Slope settings. For me, getting the transition hump in the wah sound to fall under my foot where I want it, meaning in the right part of the pedal travel, has everything to do with getting the wah to scream at the right time. These settings can also make an expression pedal "feel" more like a CryBaby or Clyde in use.What are you all using to get an insane, over the top, Dimebag-ish wah? Preferably something that screams on leads, but is also tasty for clean work.
