I was going to make the exact same points as jas, but upon refreshing to look for ninjas, jas already stole my thoughts exactly. I cannot agree enough that we should avoid having any extraordinarily high ST, due to how it's bulk we really don't need. In addition, if we're really going to argue that No Guard is risky, then moves like Hurricane and Fire Blast should be able to always KO, even with maximum SpD investment, or else a large portion of the risk in choosing No Guard becomes moot.
In regards to offense, we should have "Good" PS and SS, with a little more strength in PS. The ability to mix is important for CAP4, but it should be noted that the metagame is much more physically bulky than it is specially bulky, meaning that if we really are to rely on physical sets as much as special sets, CAP4 will need an extra edge upon boosting, otherwise between Hidden Power and the coverage moves we get, I'd find it hard to imagine that any physical sets would be good enough to use instead of things like Cloyster, Haxorus, or Salamence.
