The Stormers have been determined to change to a more expansive game. But they may have to rely on their more traditional strengths.
Defence and physicality is what brought the Stormers success in recent years and will be key elements at Newlands on Saturday.
The Stormers' shaky defence against New Zealand teams certainly make the host vulnerable - having conceded 30 tries against Kiwi opposition.
However, Stormers coach Robbie Fleck feels their record at home is far better and they will cope with the Chiefs' high-paced game.
The Stormers conceded 24 tries in three matches on tour in New Zealand and just six in two matches at Newlands this year.
The Chiefs have one of the best defensive records in the competition - having conceded just 30 tries in 15 matches. The only team with a stingier defence is the Lions - 27 tries conceded in 15 matches.
The Stormers believe they have the ability to crack the Chiefs' defensive wall and outscore the visitors.
Chiefs captain Sam Cane said defence is always a focus.
"It is half the game," Cane told a media briefing in Cape Town, adding: "The longer we can hold onto the ball, the less we have to defend."
Stormers captain Siyamthanda Kolisi pointed to the breakdown as the most "important" aspect in Saturday's showdown.
"We have seen them [what the Chiefs can do] when they get quick ball and what type of players they have," Kolisi said.
"They are dangerous when they control the tempo of the game, so the breakdowns are going to be important this weekend."
Kolisi also spoke of the 'change of mindset' this year.
"We can't [afford to] run into people the whole time or kick just because we are under pressure," he said, adding: "We have been taught to play proper rugby.
"When it is open [space] in front of you, no matter where you are on the field, have a go.
"Teams that have won the competition in recent years, that is what they get right.
"That is what we have to also get right on Saturday [the decision-making], to see what is happening in front of us."
Fleck admitted his decision to recall season loose forward Rynhardt Elstadt is because of the physicality he brings to the game.
"He will bring something different to the loose trio and the pack," Fleck said.
"We all know this is going to be a nice physical game. He has a role to play in that, [because] we need to match them physically."
