Better, load RSRDC with RFB or TMO, the convoys are more historically correct and more spread out and you can run into some massive convoys and TF's. Little bit harder than stock. I prefer to carry M10's early war due to all the failures of the M14's.
I just ran into the Yamato leaving the Bungo April of 45 on it's last one way trip. Hope I can get it before the US planes do.
Keep up the good work and save some japs for the rest of us. Here was the big convoy. I think it's the largest on in RSRD...
