I have both and the HR Terror has a smoother reaction overall compared to the Nexxxus F(p+s). My Terror is drilled pin up and has good length with a strong reaction to friction. The Triple X has a strongest backend reaction for the Brunswick line. My Triple X is drilled similarly to the Terror with a pin up, and it is a lot stronger off the spot. They can both handle heavier oil patterns. If you need something stronger downlane, then a Triple X would be a good choice.

Thanks for the response, first thing I noticed about the Terror when I rolled it was how smooth and predictable the reaction was. I was expecting a little more pop off the spot then what it has shown but nothing to make me disappointed in the Terror's overall performance, as I said before I love this piece. Being from the "little on the rev challenged" side of the tracks I'm always looking for a little more on the backend. This info is helpful, also thanks for the heads up on the Buddies deal Brickguy.
