Thank you for that Peter, but with only a 1 knot difference why go to all that expense? I have been approaching the farm strips at around 50kts, so I guess I've been about right. What I could do with is a roller to get rid of the bumps - I know they are not supposed to be flat, but I don't believe they could be so lumpy in reality, you would get shaken to bits! Frank T.
