My IXB and I are back off the African coast, but I'm happy to hear you've been able to share in the GLORIOUS hunting off Florida! It looks like you're also going to
smash my total of ~110K if you have another
ten torps left!
If you're bored next, try the North entrance to Trinidad. I found it to be even thicker with tankers, although more heavily patrolled. And you will repeatedly have to resist the urge to sink stupid Venezualen tankers who sail around in those convoys of tankers guarded by bigger tankers.
