JakeG The ‘fresh’ ones we got from Saka were good, but not ‘so good to be worth the trouble’, IMHO, particularly with the EUR/GBP rate where it is. By total coincidence, I think the mahogany roast Jampit Hit and mahogany roast Malabar Hit by Coffee Compass are quite similar to the Saka mixes in character (Jampit closer to the Gran Bar, and Malabar closer to the Top Selection), so you may want to try those as a “pre-test”.
If you want to go for a shared purchase of Saka, happy to share, and I think @TomR may be interested in a ‘Saka repeat’. Minimum dose is 1 kg/bag (they can split it in smaller packs, but sell 1kg min), though, and shipping was about €30 for a 4 kg shipment.
