Any images of the leading edges on this one?
If you look at the wing and inlets in the first photo - there isn't any obvious damage - maybe some small dents, but nothing like that Easyjet stab... I'm actually a bit surprised there isn't more visible damage to the wing and inlet leading edges.
I grew up in Southeastern Colorado - golf ball size hail was not particularly uncommon. And while I personally never saw anything much bigger than golf ball size, buddies experienced baseball size.
