I pulled the trigger on a new Konosuke HD 240mm Wa-Gyutou in Ebony today after returning my Miyabi Birchwood. This is going to be my main workhorse for prep, but I was looking at their pettys for a good option while on the line. Out of personal experience, would anyone recommend a 150 vs a 180 paired with a 240mm? Im leaning towards the 180, but its out of stock. Thanks in advance.
