The Buddies have already lost to Pat Fenlon's men at Greenhill Road in a performance the big hitman reckons was the worst of the SPL season from the Paisley men.
But, with the thrilling penalty kick victory over Aberdeen in the Scottish Communities League Cup quarter-final at Pittodrie, the Paisley men have put a disappointing three- game losing run behind them and will head for Leith in buoyant mood.
And the powerful frontman reckons Saints can gain revenge at Easter Road and start their bid to re-claim their top-six status. He said: "In the game with Hibs at our place we just did not start well enough and, in the end, gave ourselves too much to do. We did come back at them very strongly, but it was a case of too little, too late.
"So if there is one thing we can learn from that game it is that we need to start that bit better. The other aspect of doing that is when you are away at a big ground like Easter Road it is vital to keep the home crowd quiet.
"If we make the type of start we did in the first game with Hibs it will mean their fans will get right behind them and that could make it a very long afternoon. So, defensively as a team, we need to be well organised and difficult to break down and the better we hold on to possession the better.
"The win up at Aberdeen was a massive one, coming as it did after two or three disappointing results. It would be criminal not to use that as a springboard into this one and then get a positive result from Easter Road which will allow us to start climbing the table again."
The Paisley predator netted his third goal of the campaign when he opened the Buddies' account at Pittodrie and admits he is hungry to use his cup heroics as the foundation to establishing himself as a starting striker.
But, at the same time, the Englishman admits Buddies boss Danny Lennon is right to rotate his frontline.
The former Chelsea striker said: "We have four strikers and it is very much a squad game, so the manager is very much right to utilise a horses-for-courses policy. At Aberdeen, Steven Thompson and I started up top and Lewis Guy came on for me late on. But, after scoring, I am hoping to stay in the manager's starting plans."
Parkin added: "Hibs are going well and we know they are playing with a lot of confidence, so we are going to have to make sure we deliver a 90-minute performance if we want to take anything from the game.
"Having said that, if we want to get back into the top six then this is the type of game we need to be winning. So all in all it will be a good test for us but one that comes at a good time."
