My favorite set for Scolipede when I used it in the deo-d meta was 240 HP / 28 Atk / 240 Spe, primarily because it helped you against the things Scolipede was likely to come up against (i.e. Defensive Hitmontop's Stone Edge doesn't 2hko, so you are free to set up in its face if you have Swords Dance (more on this later)). You also avoid a 2hko from Scarfgon's Earthquake, an ohko from Machamp's Stone Edge, and a few other nifty calcs. This can mean the difference between getting down another layer of spikes / slamming something with a Swarm Megahorn or losing your centipede, so it's worth considering / testing.
SD set looks fine. Baton Pass should probably the primary option over Rock Slide, mostly because of your ability to swiftly force Gligar's head up its ass. The ability to beat Zapdos is nice if that's important to your team though.
Everything was beautiful. Nothing hurt.
I'm back, baby. Look for me in 5th gen UU!
