I Have a Diana 52 .22 flavour with a Vmach kit fitted,runs sweet 11ft/lb with
RWS Superdomes.
Agreed it is a little heavy,but don't let that put you off.
The trigger is not as good as some rifles,but there is a mod that can be done.

I have done just that but yet to test the rifle.
Anyone who uses my rifle at the club always hands it back with a grin on their face,some I have to ask for it back
