most conventional thinking agrees with zones and rebounds, primarily because you are forcing outside shots, which, generally, create longer rebounds making it more difficult for your primary rebounders (4 and 5s) to rebound. It is also harder to "box out" as you are not guarding a man, but an area.
However, if you have guards dedicated to rebounding and work hard, you can rebound in a zone just fine.
LK does not seem to play a lot of zone - unless it has an element of a trap or pressure.
