mult to your mix and stem tracks instead of printing through your stem tracks.

I do both Offline Bounce and Realtime print.

OLB if it's for a quick approval or temp.

Realtime if it's for delivery (and punches for fixes)... I've found enough mistakes or things I want to tweak in my final playback that it's 100% worth the extra time. It forces you to sit and watch it.

Offline bounce bit me ONCE... a reverb didn't change IRs correctly... that was enough for me never to trust it again for delivery (I don't remember which reverb and I could never re-create it... but still)

you CAN successfully destructive punch into a file that has been offline bounced.... if you want to go that route.
