Thistle boss Stuart Davidson can't wait for Saturday's replay versus St Roch's in a winner takes all clash.
The Barrfields side had to settle for a draw at Barrfields Park but will go in all guns blazing for a quarter final spot in the Macron Scottish Cup.
Ten men Largs dominated the second half, and will hope to finish the job at James McGrory Park, 1.45pm kick-off.
The match will go to penalties if it is a draw after 90 minutes.
Davidson hopes that the Largs players can thrive in the potential powerkeg atmosphere: "This is what the Scottish Cup is all about - we want to go away to these places and enjoy it.
"It will be a right good atmosphere and a good old fashioned cup tie where we will roll our sleeves up and go forward in battle.
"I have every faith in the boys. I am sure St Roch's will be ready too, and we might need to make some changes as well.
"I am looking forward to it."
