Lock didn't intend to change things up at Border's last training session last night, preferring to clarify on plans already introduced and talked about throughout the season.
"It's no use changing things now and we are in good form. The guys are in the right mindset and other than losing Fraser Middleton for the rest of the season with a knee injury we have a full squad of 22 ready to go," Lock said.
Pirates coach Red Morris described his side as caged lions awaiting release after a lack of match play in recent weeks.
Pirates had a bye, followed by two soft wins where they racked up 199 points to nil and then a snowed out game.
"They're like caged lions rearing to go," Morris said.
"Forget about past performances against Border, this weekend we are treating the match as a final and if we can't play at home Waverley is the place we'd prefer to be, they have great facilities."
Morris has the luxury of an injury-free squad, so will be able to bring his full complement, including the old hands alongside his Samoan academy and Samoan sevens representatives.
"I don't know how far this team can go. We bring a physical game that others sometimes struggle against. We trained in the rain on Monday and that's what we expect to get this weekend, so we have trained to the conditions, just like a racehorse," Morris said.
In the other premier semi, Marist has the added incentive of it being the club's centennial year when it lines up against McCarthy's Transport Ruapehu at Spriggens Park on Saturday.
Coach Jason Hamlin goes into the match with no injuries, but has lost the services of lock Lake Ah Chong who was blue carded a few weeks ago and has still to get a clearance.
"Other than that we have a full team aboard," Hamlin said.
He also agreed Ruapehu often grew another leg at semi-final or finals time and for that reason and the experienced heads the northern side will bring, Hamlin is wary.
"They are used to playing at this level and if we don't bring our game they will squeeze and squeeze until we break, so we'll need to play rugby. We planned our season in sections with the first to get up and running, then celebrate the centennial and now the focus is on bringing the premiership home.
"There are a couple (of Marist players) who have stayed on this season - old heads - to help win the premiership in our centennial year and that's a good motivator."
With a weather bomb forecast Hamlin is praying it won't hit Spriggens Park.
"We'd rather play on top of the ground, but I suspect they won't mind a wet track."
Ruapehu coach Daisy Alabaster wasn't so sure.
"Not sure how much of this weather forecast we'll get, but it won't matter if we don't turn up on game day," Alabaster said obviously still smarting from the 48-17 hiding from Marist three weeks ago.
"It was 38-nil at half time, so we did win the second half, but we can't afford to sit around and watch like we did three weeks ago. Marist are the clear favourites and we are the underdog and quite rightfully so.
"We will come with a team of sorts, although Campbell Hart looks to be out for the season with a groin injury, while Craig Clare will be touch and go. We'll see after the final training run whether he is in the starting line-up. And Ginger (Andrew Evans) is also still suspended. Evan if Clare starts he hasn't had much game time lately, so really we'll have to see what happens on the day. Marist has been together four or five years now with a pretty handy coaching team, so they will be hard," Alabaster said.
