Hey man, I looked at both of these skis when I was trying to find my one-ski quiver. Both are pretty stiff skis that do well all over the mountain and their weakest area is the park. I LOVE Prophet 100s and consider them the best one-ski quiver if you aren't into park much. The shred a hardpack turn, float pretty well in pow and are awesome in trees. If you have silencers, just keep those for park days and snag either of the skis you mentioned. I will say that the biggest difference between the two is turn radius. At around a 180 length, the P100 has a 17.2 m radius and the Snoop has a 22m. So, if you like to really hit a hard turn, the P100 dominate in that area.
Hope that helps!
