best submarine mod?

[mr. engino]

since hl submersible parts are not functioning properly and therefore unusable, i would like to know which submarine/submarine parts mod is the most preferred. i know of three of them: ballistanks, ballast water tank, and submarine parts. if there is a better one, please let me know!

USI Submarine Pack by @RoverDude I find is the best.  It's a bit hard to use at first, but once you get the hang of it, it's awesome.

After some testing, I found that VesselMover is all I need. I'm pretty satisfied with the stock ways (most notably Juno engines or ore tanks). Can't say those solutions are practical or realistic, but fun and sufficient. My favorite KSP fact these days: air intakes work underwater.
