In 2001, David, who has played under Dunlop Sport sponsorship for most of her junior career and WISPA career, signed a two-year deal to play with Head rackets with local conglomerate Mulpha Sports. In July, David won the World Junior title for a second time, beating Omneya Abdel Kawy in just 17 minutes with a score of 9–2, 9–4 and 9–2 in the final. She remained the only female squash player to have achieved this until 2007, when Raneem El Weleily won her second World Junior Championship. David also won the individual event in the Asian Junior Squash Championships by defeating her compatriot Tricia Chuah in the final with a score of 9–5, 9–6 and 9–0; and helped the Malaysian team to the team event title.
