I'm very impressed with Choice Scarf Infernape this gen. U-Turn, CC, Flamethrower/Fire Blast/Overheat, HP Ice is the set I've been using - it's pretty handy as a Scarf user. U-Turn to scout, CC and fire move for STAB and finishing off stuff, HP Ice to kill +1 Salamence and do big damage to non-scarf Garchomp.
In fact, pretty much the same set was posted on the first page, but I really like it.
This particular set has competition from Flygon, which can do similar things (revenge kill some dragons, pick off weakened foes and scout), but I like the ability to know I can kill +1 Salamence without a speed-tie, and it can hurt Skarmory a lot more. On the other hand, resistance/immunity to every entry hazard is still an excellent reason to use Flygon since it will be switching a lot. Really just depends on your team, but I really like this Infernape set.
