Go for it
Early days you all need to go for it to get th eexperience.
Start with fully coupled auto hover and see what you can achieve with it but more importantly what it's limitations are(eg glassy sea and doppler mislock etc)
and then develop onto using less automation to allow you to deal with situations that the automatics can't help you with.
This will take time, but when you have an experience bank then you can reduce the training burden as crews have experience to fall back on.
Before I left we were capable of doing full manual letdowns at night for the hell of it, just so we could if needed. All of my rescues at night overwater had an element of manual control due to either conditions or time.
Have fun
