Those look great!
On the vac seal, I really like to let it sit in the fridge over night or even another day before freezing.
Ya know, they always say "BBQ tastes better the next day" lol...
Let those juices meld for a day before freezing.
Then, retherm in the vac bag in a pot of hot water say 190°F after they thaw.
We had a vac sealed half rack a few days ago, if anything the smoke flavour was much more deep than the fresh ones. Just as good and tender as the fresh ones too, so that's a win in our book.
@Frank - You're right, we always eat quite late and the leftover stuff gets put in the fridge once cooled until the following evening when we do the vac sealing and freezing.
Edit - we always boil up in a big pan from frozen, set them in with cold water and bring slowly to boil, then simmer for another 30-45 mins and always come out good.
