"It was awesome, wrote Broad. "That in particular was what inspired me to go for it.
"He reckons it gave him an extra six years on his career, that he became meticulously accurate, had such control at the crease that he wouldn't bowl a bad ball and that it gave him more bounce.
"These are all the same reasons that I want to make a change. If it's good enough for one of the best bowlers in history, why not me?"
Broad is hoping that his higher release position and shorter run-up will provide him with extra bounce, which could come in handy as he prepares for what he believes will be his final home Ashes series.
"This time last year I did a lot of work on my wrist position and then took six wickets in the first innings against New Zealand in Christchurch, so I hope the changes to my run-up will have a similarly positive effect," he said.
England play three tests against the West Indies next month, and a one-off match against Ireland in July, before Australia visit in August and September for the Ashes.
Considering Australia's test struggles at home against India, and England's recent 3-0 series sweep in Sri Lanka, England will likely be favoured to win the Ashes, in their home conditions.
And, if Hadlee's advice proves helpful for Broad, then England could be well and truly primed to take back the urn.
