After experiments with b129, I feel this is without doubt the best update yet -for me.
Less icons (tho still way too many labels ) , better hydrophone (I think its significantly better) , more realistic movement, stability, etc- still a few non-lethal bugs
I like "Full" manual targeting. For me that means: Not locking onto targets( lock-label needs to go), No Stadimeter, ship ID manuals, TDC, or map plots for measuring target parameters. Just Mk-1 eyeball , binos and scopes to estimate Range, Speed, and AOB. Then plenty of stealth to get in range.
I really like UBoat's deeper dark nights. The hardest thing for me is learning how to order these Bots around and keeping them happy

. when things go South.
