All the guns you mention are over 9+lbs ,probably 10+ with a scope and mounts fitted.
Those heavier springer’s generally absorb the recoil better.
Unfortunately some people will find them to heavy for unsupported shooting.
I have the hw97 and Tx200 and wouldn’t want them to be any heavier.
My Webley Tomahawk and bsa superstar are about 8lbs unscoped and are a nice weight for me.
If the springer is to light and full 12fp they can be a bit twitchy.
