Thanks all.
If anyone comes across a good shooter but rough around the edges (~$500), I'm trying to pick up a new field gun to try out this year and the Flues fit me really well with the 3"+ Drop at Heel.
Trying to assess a gun over the internet through pictures is tough, so I'm trying to do my research and make sure I dont buy a dud which is a real possibility in the price range I'm looking at.
I suspect if the gun works well for me I'll be upgrading to a nicer Grade in the future, just starting out rough & ready
