I call this bean my nemesis but with time its become one of my favourites. I find it needs a lot of attention after FC to keep the roast from running away or stalling.
I currently prefer a quicker ramp to First Crack (9-10min) followed by a slower ramp to second crack, but I stop the roast a couple of degrees BEFORE second crack at about a CS 8/9. This enhances the blueberry flavours. It does work as a darker roast though I found it quickly turned a bit ashy if pushed into rolling second crack.
others recommend a blend by roast some light and some dark and then blending.
try a couple of profiles and roast depths and see how you like it.
