I picked this size for its portability factor. Didn't want to lug around a 130 and wanted a bit more resolution than a 100 could give. Can't wait to try it out.

Super nice scope!
What's the size difference between the 120 and 130 (besides 10mm on the objective)?
I know that when you increase diameter, the area/volume increases exponentially, but I still wouldn't have thought that there'd be that much difference between a 120 and 130 (assuming similar focal ratio).
