Coach Vishal Marwaha believes Hillhead have performed well in the second half of the league season and they played well to edge Edinburgh University 3-2, after being 2-0 down, in the cup semi-final.
It is the first time in the club's history that Hillhead have qualified for the showpiece game, but Western are out to spoil their day and have targeted a domestic grand slam having already won the indoor crown and the league title.
Marwaha said: "We're really looking forward to Saturday. It’s been a long-time since we were last in a cup final and they are always great occasions."
Western have a full squad to pick from and will look to top marksmen Rob Harwood and Andrew McConnell to take them to victory.
