spring onions

just thinking about ordering  my spring onion seeds for growing next season i was looking at several varieties the cheapest was white lisbon  being a bulb type spring onion that we normally grow but then i thought i mite give the non bulbing type's  a try although the non bulbing type seeds are a bit more money i looked at a variety called Guardsman said to be Hybrid white lisbon/Japanese cross that's resistant to bulbing

although we grow and like our spring onions in our salads i find the bulbing types do tend to give me tummy upset so I'm really looking for a milder  spring onion if that's possible and i thought the non bulbing variety would not be as strong as the bulbing ones?

I've also looked at other spring onions varieties non bulbing varieties like Darcy carel and entita but i think i mite go with Guardsman any comments on the above varieties  or any other varieties would be most welcome

I've grown Guardsman the last couple of years. They grow quite tall and are mild flavour. They stood well into winter without any sign of bulbing. I'll be buying more seed for next year.
