Most are good advice/ I'd like to add, go broodlords when u tech to hive fast, and it usually helps to mix a little bit of baneling to all the roach to quickly kill the helions since baneligns do good dmg vs them and while helions don't do that much vs roach, they can soak up a lot of hp for tanks/thors.

Also, if you can't be bothered to play a macro game, just go a giant 2 base nydus roach all in
