Let's jump start your thoughts on the subject.
If the parallel LC trap is of infinite Q, and
therefore presents infinite impedance at its
resonance frequency, how is there a voltage
developed across it if technically only one
end of it is connected to anything? On the
other hand a quarter wave stub used as a
high impedance trap is tuned to the operating
frequency. Quarter wave stubs and LC traps
don't act the same. Wisdom is when you get
a glimpse of why. You're asking some very
good well thought out questions.
