Replying to this with my thoughts as I go through and try them!
I’ve given the Maraba a few brews in the v60 and to me it makes a lovely cup! I did make an error while ordering this one - I ordered filter pre-ground by accident! The good news is is a perfect grind for my v60 but there’s definitely more taste to be had if I’d ordered whole beans like the other ones!
I've had some really good times with beans from union. They're quite good quality for the price. At least they were when I tried them, not sure if their prices have gone up. Either way, you have some quality beans there. Enjoy!
