I have fired almost all makes of springer. However i have never had the opportunity to try a modern Diana. I use AA for obvious reasons,hard to beat being one of them. Has anyone tried the Airking sliding sledge model? The fact they are heavy is a plus in my opinion. How are they for build quality,reliability and maintenance? I thought i had finished looking for the elusive ,"best" springer, But i have this sneaky feeling that i may be missing out on something by not trying a Diana model.Any comments really appreciated,sensible ones,lol.
