"It's been close to the quickest wicket I've played on this year," said Cummins.
"With a few of us guys trying to bowl quicker, I think it's going to favour us. I think for us having all our games in Australia, the bouncer is really important.
"You can bowl two of them an over and if you execute it well it can be a dot ball, which especially towards the end of an innings can be gold.
"It's definitely something we're going to continue using."
Cummins was carted for nine fours by minnows Scotland in Hobart, to follow on from his last outing in Auckland against New Zealand, where he was also expensive.
But any alarm on the part of selectors was tempered by the exciting right-armer firing back with three quick wickets.
Cummins' first World Cup - the biggest moment of his still fledgling career - has been a roller coaster to say the least.
For the opener against England he was benched, with Hazlewood the favoured third seamer. By the next game he was elevated to the first-string attack, only to break down with a side strain, and raise concerns over whether he would feature again in the tournament.
Now Cummins is back and the position is his to lose.
Hazlewood has had a fine summer, but selectors feel Cummins' speed and variety gives them better strike-power in the middle and latter overs.
Captain Michael Clarke is backing the youngster by throwing him the new ball to break up the left-arm combination of Starc and Johnson.
Many in cricket are wondering whether selectors will back Cummins in test cricket this year in the West Indies and on the Ashes. Powerbrokers are treading carefully, keen not to over-expose Cummins too early after his years of injury struggle.
