i'll end up w/a 160m long dipole as it's my lowest freq and
see how it goes

For the 160m band, the antenna only needs to be 80m long.
The rule is: Make the dipole 1/2WL long on the lowest
frequency of interest. And actually, using a tuner, you
can get away with making it 3/8WL long on the lowest
frequency of interest. So your dipole only needs to be
~60m long to cover 160m-10m.
