LOTS more variables - but here would be a starting point:
Wet track use? Something aggressive with softener. Aggressive PRW.
Dry track use? Aggressive bite but without softening. Aggressive PRW.
Low bite track use? Aggressive bite with or without softening. Aggressive PRW.
High bite track use? Mild conditioner and just something to fire the tire off.
It's really not as easy as listing tracks into those 4 categories. Tracks that build heat in the tires, big momentum tracks versus bullring tracks, dirt/clay type, moisture content, Sealed up, prep line, etc etc.
Sometimes you need internal prep, sometimes you do not (speaking of Burris here.)
Give us a call if you would like to discuss our prep line and have more specific questions.
