Morning Pauly, as Tony has said, everyone will give you their own choice of onion sets to grow, my own personal choice was Sturon & Turbo.. both decent size bulbs but also stored well. As for planting them, make sure they're pointy end up.. unlike Tony I've never had an issue with just pushing them into the soil and root balls have always been good, but I've always made sure beds are cultivated prior to planting which makes it easier for sets to be pushed in.
