I most certainly would have a go if you were not bloody hours away from me. Personally I would be confident to get into the water slowly and settle down, keep still and let the fish investigate, don't expect there would be much cause for concern about being stung.Haha i did think of doing that as the camera on end of the stick isnt to accurate are you nominating yourself for the task lol. Thanks for the comments
