That is by far your best solution.
As the architect of some competitively scoring FD stations, I agree
with others who have noted that stubs dont have nearly enough Q,
and that heroic measures are needed to achieve even a little in-band
rejection.
Your choice of 100 watt radios like the K2 that are relatively clean
and have very good receivers is the right approach. TS850s make
good FD radios too. Avoid cheap radios (FT100, IC706, IC746, etc.)
like the plague. Their receivers overload easily, and their
transmitters are broad as a barndoor too.
Likewise, having high flat dipoles for stations on the same band at
right angles to each other helps a bit. So do baluns, IF they are
good enough to take the transmission line out of the picture. But
dont expect much help from low dipoles or inverted Vees.
