Your roast looks pretty good to me "sd".... 8-)
Probably the only difference between yours and mine is that I take it a little slower to reach Rolling FC, probably 13-13:30 minutes and pull it before SC snaps start at around the same roast colour for a total roast duration of about 18:30-19:00 minutes and then immediately cool.
Tend to leave these rest for 4-5 days before cracking open the bag but thats just me. A good idea is to start sampling almost immediately as youll then find where the sweet spot is for you. Ive tried brewing in all the usual ways but I guess using the AeroPress or a Double Ristretto would be my personal favourites. Another great PNG bean for sure :)....
