Ginge,
Partly, it depends what you are flying, but whatever you are flying and wherever you trained, 50hrs total is too little to fly safely in and out of Lundy.
It's fairly short, fairly rough, has a hump in the middle and very challenging winds at times. Also, the perspective is confusing approaching to land on top of a high cliff.
Insert Lundy into your first summer of strip flying. Don't do it as your first or near first experience of strips.
