lets see... So, you should use it as a lead. or as a baton passed sweeper, So what I would recommend these things.
252 Speed, 252 attk, 4SpA
This is a pretty good way to counter a setup, as it will counter the Setup moves like Sticky web, and then leaves you free to hit them the next turn or taunt, so you can suckerpunch them to death, but flamethrower is an option for things like Forretress. Fire blast is less recommended because of the accuracy issues.
Or you could use it like this
252 Speed, 4 Attk, 252 SpA
Alright this may be confusing, seeing as how the Absol has most EV's in SpA, but is mostly physical, and yes they can be swapped but it has a purpose not being like that. That is because it works with...

Jolly Nature, Speed Boost
252 HP, 252 Speed, 4 Attk
Baton Pass Scolipede became less common with the Baton pass limiting... but is still very viable. The EQ is just there so that you can have an attack... but Protect is so that you can at least build 1 stage in speed before Baton pass. Iron Defenses is also an option as it can help remove some frailty from the Absol.
