Of course I want to see teams before S19 like Colin/Christie, Dustin/Kandice and even Charla/Mirna again, but seems if there's next All-stars then only teams from S19 onwards will be chosen, if so here are my picks:-
S19 - Andy/Tommy - not like them much but they surely have unfinished business
S19 - Bill/Cathi - most competitive elderly team in recent seasons
S20 - Brandon/Rachel - hate this team but seems will be chosen for ratings like Rob/Amber
S20 - Vanessa/Ralph - Like Vanessa, good to have them if Rachel is chosen, but seems they split up already
S20 - Mark/Bopper - Must have, production likes them much in their season
S21 - Jaymes/James - Must have, production likes them much in their season
S21 - Natalie/Nadiya - Good to have a cunning team, though they are annoying
S21 - Abbie/Ryan - They also have unfinished business due to the flight drama for their elimination and also the only team have chance winning 2m so far, and good dynamics with J/J and N/N
S22 - Dave/Connor - Must have, production likes them much in their season
S22 - Pam/Winnie - Good to have one competitive F/F team in the group
S23 - Tim/Marie - Star of this season, would pick them if they do not win this season
Don't mind Brandon/Rachel not chosen, if so then Vanessa/Ralph need not appear as well, which makes room for potential S24 teams or Joey/Megan (S22), Jason/Amy (S23) or Nicole/Travis (S23)
