Opinions on telescopes wanted.

I am looking for opinions please. I am building a new home and, of course, an upgraded attached observatory. The setup will be housed in a 14.5 ft pier tech dome. The scopes will be a new 20" planewave and my existing 14 " Celestron hyperstar (for Mallicam), Stellarvue 105mm and Lunt 80mm solar scope which currently are controlled with ACP and Starry Night.. All will be mounted on an ASA DDM 160 mount.


If faced with a choice between upgrading the 20" planewave to a 24" and keeping the Stellarvue 105 OR staying with a 20"planewave and upgrading the Stellarvue 105 to a larger refractor like a Stellarvue 160 or a Takahashi 150, which would you do?

Thanks,
Doug
