I loaded up Exhaust Smoke, by Racerboy, modified for Water Streams by Philipp Thomsen.
I followed Danlisa's instructions to remove the binocular bearing marks (Free Cam mod puts them back in).
I followed Ichso's instructions for removing the the big compass from GWX.
I installed the TDC Dials in Periscope View, by FLB_Sale U-999.
I installed U-Jagd Tools, by JoeGrundman.
And finally I installed the Simfeeling Six-Dials mod, by FLB_Sale U-999.
It took a lot of fiddling and fussing to get it all to work together, but I'm happy with it now. It might seem excessive or obsessive to some, but I've played enough games in my life that I don't get a thrill out of winning anymore. I just want to pretend I'm a U-boat captain and imagine it's all real.
I'm still not ready to play quite yet. I still have my own Ship Names mod I'm working on, and I don't want to sail until I'm ready for my first phase release. I think I'm now going back to Torpedo School and bone up on my manual targetting.
