Voyager 2 has been flying for over 40 years and it's still only twice as far as Pluto's orbit. New Horizons is actually faster than Voyager 2. Gravity assists to build speed aren't hard to find.
The Voyager probes benefited from a planetary alignment that allowed it to visit most of the outer solar system, which isn't a concern for an interstellar mission.
