Both teams come into the T20 Grand Final in ripping form, having won their semi-final clashes in convincing fashion.
Neither side has made a T20 final since Melville took out the title back in the 2013/14 season, while it has been an even longer drought for the Lions.
Both sides are in great form with the bat, with Sean Terry (225) and Fraser Hay (191) sitting in the top three for runs scored in the competition, while the Lions are the highest scoring team in the league.
In a match that is looking like it will come down to the wire, the Lions and the Storm will need to apply pressure and take advantage of their opportunities early.
A lot will rest on the shoulders of Tim Monteleone and Michael Hart, having lost David Willey and Jason Behrendorff, the pair will need to be at their explosive best with the ball.
