Using v15 now, and for my taste it pitches and rolls just a touch too much.... but thats just me.
Something about Sh and the way Subs ride in the water....
Tend to "Bob" too high, and not "Smash" into waves with the force something that heavy would.
Hope you can find the Happy Place between "Sub on Rails", and "White-Knuckle" Ride.
Will try this new Version.....
