Newcastle Eagles and London Lions will meet in the BBL Play-Offs final after reaching Sunday's showpiece at the O2 Arena in contrasting fashion.
The Eagles beat Sheffield Sharks 118-78 to complete a 209-168 aggregate win.
It will be their fourth successive final and they were inspired by 28 points from Rahmon Fletcher.
The Lions lost 85-77 at Cheshire Phoenix, but went through by a narrow 158-153 margin after winning Friday's home leg of their semi-final 81-68.
Zaire Taylor, last season's Play-off Final MVP with Worcester Wolves, shone once again, scoring 32 points for the capital club - the last few coming from the free throw line as he settled the contest during a nervy final minute following Phoenix's 17-3 start to the fourth quarter.
The Eagles are likely to start the final as favourites as they look to complete a second clean sweep of silverware in the space of four years.
Fab Flournoy's side went into the second leg against the Sharks holding only a single-point lead from the first match in Sheffield.
But the BBL Championship, Cup and Trophy winners dominated the return, racking up 31 assists as a team.
"Players are playing hurt, we haven't really practised much, but I was delighted with the heart and togetherness that we demonstrated," Flournoy said.
"It's has been a long season but to play through that season and produce what we did on Sunday was very gratifying."
