I've used angled scopes a fair bit over the years, and will be sticking with my straight scopes. They prefer women, just like I do...
Packability is certainly an advantage, as you pointed out, especially designs like the Swarovski or the new Razor that don't have focus knobs sticking out.
I'm glad to see the Razor lose the "sticky outy" focus knobs. I know of two spotters, one a Razor, that ended up with bent knobs.......
