Was going to say, if you're going for the strongest flavoured salt & vinegar crisps, Discos are king. McCoys have the best flavour. And if it's punishment you want ... me and a couple of mates used to play this game/challenge on the way back from away games. Get a big tube of salt & vinegar pringles, see who can eat the most in one mouthful. Rules are that they must all be in your mouth at the same time, your can't spill any whatsoever, and you're allowed to use one hand to put them in your mouth & optionally hold them in.
The salt & vinegar dries your mouth out just in time for the pringles to start forming in to shards, rich feel like you're ripping the inside of your mouth to bits. Overall record was 19, held by my mate Rich. My PB was 17 Pringles (did 19 once, but there was spillage).
