A great example for me is when Rosdahl compared the No Rules Exist, Dare Devil Trick, and No Rules. On most house shots, they will cover nearly the same amount of boards. The Dare Devil Trick reads much earlier and has a slower response time off friction making it ideal for fresh consitions especially when the backends are crisp. The No Rules responds a bit harder off the spot in comparison to the Trick. The Exist has some of this same quickness that comes from the core, but the cover keeps it from being sharp downlane.
Basically, the key is to take in response time as a factor along with the three phases (skid, hook, roll), cover characteristics, and most importantly, surface.
