I went through the same problems in making my decision too, so I'll share my thoughts in the hope it helps in some way.
I wanted a scope that I could dial with reliably. I wanted a pretty high magnification, but wide enough for general use. I wanted it light as possible. I wanted enough adjustment to reach way out there on targets with a 20 MOA base. Oh, and awesome glass, especially at low light. And while I could spend some on glass, I couldn't do 2 or 3k. Add to that, for a hunting everywhere scope, I wanted locking turrets, and as you can imagine, something had to give. Low weight really is probably the most narrowing requirement. In the 13-17 oz range, there are so few choices. The 6500's, the VX3i's and Swaro are all I can think of in that range, but I may be forgetting one.
Compromises, had to make them. Maybe figure out what you can live without....sounds like giving up on the dialing might make the swaro work for you. No doubt, the glass is beautiful and they are light, but I don't like holding over, so that would not work for me, but many people prefer that.
If you can give up some range, VX3i's are light and you would not need a cant with a 30mm. Not in the same glass class as swaro, but still great stuff.
You could also take on a few ounces, or maybe lose some weight elsewhere to make up for it, and go to a VX6 or HD5 or other option. Don't know what rings and mounts you plan on using, but there is a source for talley ultralightweights with a cant cut into them. They might save you a few ounces depending on what you have planned for mounting, and you can still get a cant.
On the quality of the glass....everyone's eyes are different, so YMMV...but my experience is one of having less than I needed and regretting it. You can certainly take that 'buy once cry once' saying too far, but I have been in the situation under legal hours where I could not see due to my optics, and the difference at the last moments of the day where quality separates itself, to me, is critical. Always see the best stuff in the last minutes of legal shooting light, it seems. So I would stick to this one if I were you. Maybe go to a local store, take what you already have, and see if they will let you check it out during the late hours outside. Cabelas will usually let you do that, my LGS will as well.
Anyway, hope that helps, curious to see where you land!
