I got a call from On-Stage (the mfg of my mic stand) and they gave me a FANTASTIC recommendation: these goose necks are threaded on both sides, and are flexible removing the need for a rotating ball adapter for certain mics/cameras.

I bought two 19" ones, so now my 30" boom pole will be able to reachabout 68", be flexible more than half that length, and cost me a grand total of 16$ for the solution, rather than 30 for a painters pole that i would have had to adapt, or a replace the whole boom pole for god knows how much and adapting it to the tripod mount on the stand somehow.
