Thank-you everyone who replied to this.
There is a lot of love for Vela, which I was not expecting.
I had better go back and study the Vela thread - 🧪 Early Information on the January 2020 HOTM (Vela) - before I feed those 'scopes away.
Assuming no Vela comes along, I am slightly tending towards Magni … but my mind does flip-flops quite regularly!
