Even though the new Scout/R is reactive, they have been changed to a regular pancake style weightblock, and that doesn't give them much dynamics to work with.
Dulling (sanding) the cover will give you more hook POTENTIAL, but depending on your release, may or may not have a large effect on your hook. If you have higher speed, lower revs, higher degree of tilt, or lots of axis rotation, you have factors that tend to reduce a balls total hook, ESPECIALLY when the balls dynamics aren't strong enough to overcome these factors.
Visit the shop and see what they say. You may want to look into a ball with a stronger surface AND a stronger engine (weightblock) to get that extra hook you're looking for.
Good luck
