Leitrim struck a psychological blow against Louth in the group stages, winning by eight points but this final looks like being much closer.
Louth suffered yellow and red card woe on that occasion and they were without key attacker Kate Flood.
The Wee County have bounced back impressively since then, scoring big wins over Antrim, Derry and Offaly en route to the Final.
Leitrim followed up that opening day win with further successes against Derry and Antrim, to set up a semi-final against Limerick.
Michelle Guckian, who’s been brilliant to date in the League, led the way with 1-6 on that occasion, while Louth will look to the scoring prowess of Flood, Niamh Rice and Lauren Boyle in the Final.
Leitrim will look to emulate their Division 4 title win of 2010, while Louth are aiming to atone for their 2018 Final loss to Wicklow.
