Best summoner for potato computers?

Alright so quick question for you veteran summoners! I'm choosing between three different summoner builds for league start. I'm on a potato pc, which one of these do you think would be best for good fps even in blight maps etc?

1. Zombies and spiders with spectre support(carnage chieft)/AG skitterbots.
2. Spiders with spectre support(carnage chieft).
3. Slave driver spectres with AG/skitterbots.

I've tried only zombies with carnage chiefts before they ran okay, do you think adding spiders will be a problem? (never tested spiders, ran spectres before but not slave drivers..)

Thank you :)
