There are actually a lot of different variations of Scolipede running around. There is a Sash lead with Megahorn / Spikes / Aqua Tail / (Toxic Spikes / EQ), as well as a more offensive set with LO which is Megahorn / Aqua Tail / EQ / Spikes. Rock Slide can also be subbed in to either of them. Some people also run a bulky Scolipede to take advantage of its resistances, though I don't have much experience with this.
