May very well work just fine but the heavier the scope the heavier built I think a mount should be. I had an old B square mount years ago that would flex like crazy and looked like it could break at anytime.
To its credit, it never did but I have been suspicious of light mounts since.
I agree a mount should be stronger for a heavier scope, but weight of the mount has very little to do with strength. Something like the Aero is already pretty strong, and a cheapo B-square mount is a pretty poor comparison for any quality mount.
I had one of those Weaver thumbnut mounts mentioned above; it was just more chinese garbage. The dumb thing leaned to one side when mounted on the rail, and had to be cranked down with a tool to stay tight. Not much point in the "thumb nuts" when you have to use tools to keep the mount tight.
