I received my greenbeans on Friday and did a roast yesterday. The New Guinea A roasted well in my popper and came out a treat. Then I did the Kenya AAs. I use a B&D popper, I noticed that the Kenyas were a bit bigger bean and they did not rotate in the popper so I had to agitate them for a while to stop the bottom beans burning. After doing this they started to circulate and all went well.
Just a warning for the unwary, cant waste good beans!!!
