I have an AP130EDT and an 8" f6 Newt built on a superb old Meade RG mirror that is optimized for lunar and planetary but in a solid Hastings tube with Protostar air spaced flocked liner, 1.5" quartz secondary, Blacknoise vibrationless cooling fan, low profile Feathertouch focuser.
I have had the AP since 1995 when I was in my 20s and used it a lot for lunar and planetary over the years and it did superbly well even in Colorado along the front range with rapid temperature drops and iffy seeing and gives very immediate views. As I'm getting older however, I'm having more of a challenge with the 130 at 250x and up due to floaters and such in my eyes. I don't use binoviewers personally, usually I find it hard enough to keep my dominant eye lined up with the eyepiece and I like the less glass approach.
I find the Newtonian more effective for me these days. It will let me use up to 400x or so on Mars and a given magnification is about 2x as bright and somewhat better resolution. I typically use mine on a DM6 on a Stellarvue TSL6 as my 2 step "grunt and heave". One trip for the mount, another for the OTA. I included handles on the OTA at center of gravity for carrying and another couple to give leverage to rotate the tube if desired. With the fan, it cools down within 30-40 minutes max and is inert thermally after that due to the air spaced liner killing any convection off the tube walls. With the solid tube, I rarely need to tweak collimation and f6 is pretty forgiving with a pretty wide sweet spot.
I don't think the Portaball is going to work as well as what I built from a thermal or mechanical standpoint, the truss is open to air currents from you and the ground, the upper tube is extremely short and won't really handle anything heavy up top. But if the price isn't that much more than a new mirror from Zambuto, you could always build a custom tube for it.
