Xtal oscillator issue

Hi,
Conventional wisdom says that an inductor in series with an xtal will pull it low, while a cap pulls it high. That said, I have found pulling them low is more challenging than high.
Putting 2 (or more) xtals in parallel is sometimes tried to increase the pull range. Much depends on the circuit values that are used.
Can you post the circuit you are using? Also, do a search on super CXOs for more info.
