switch 10s are only good in my opinion if you get a good grab, and can do sw 9s sw7s sw5s. The reason they are so popular in comp is that its the best trick that wins, and ppl are doing good sw 10s, so why would someone do a good sw 7, its fucking retarded, they dont want to win then, so thats why a lot of ppl do 10s in comp, because they want to do good
