Ah, bugger. I love too many of these. Can I do it by flavour? I'm doing it by flavour even if you say no.
Meat flavours - Walkers.
Spice - Monster Munch... Doritos is a close second.
Salt - Kettle/Tyrell tie.
Onion - Pringles.
Cheese - Quavers.
edit: wait my fave crisp brand is Chipsfrisch what am I doing.
