A finals spot is on the line, as both outfits sit equal seventh on 36 points and trail sixth-placed Nagambie by nine points.
If the Lakers are unable to defeat Kyabram this round, then an outright victory to either side could have them pinch sixth spot.
But for that to happen, a special bowling effort will be needed.
And it's a good thing United and Waaia have the potential to roll through sides quickly and with extreme ferocity.
In round six, United left heavyweight outfit Katandra shocked, as it ripped through the Eagles’ batting line-up for a miserly 54 runs.
On that day Ethan McLaren starred with the ball with stunning figures of 6-7, while teammate Sam Nash contributed to the damage with a handy 3-22.
United went on to post 262 with the bat — thanks to an impressive 85-run knock to wicketkeeper Keegan Armstrong — but was unable to seal an outright win.
And only recently, Waaia's fearsome bowling brigade tore Tatura apart for 50 runs at tomorrow's venue in round 11.
The Bombers’ Jesse Trower collected career-best figures of 8-12 from 21 overs as he ripped through Tatura's batting order.
But just like United, Waaia was unable to land the final blow on Tatura and walked away with a first innings victory.
In recent hit-outs, the away side enters this contest off a disappointing loss to Euroa on its home deck, in a game where its batting stars failed to get the runs ticking over.
And for the flying Bombers, they will fancy their chances of capping the year with another strong win after dominating Central Park-St Brendan's with the bat and ball last round.
