Flex drapers are a very good feeding head, but let the 1020's do the tall weed escapes. A flex draper only has 2 pivot points and by design can never be as flexible as a 1020, if your land is relatively flat than this is not an issue. Extending the center cylinder to cut closer may work in some areas, but our area has an abundance of stones,and yes stones will make it over the high front lip. Wet conditions will soon discourage you from using too much header pitch as damp dirt will get under your center canvass. A properly adjusted 1020 is a tough act to follow if it is properly adjusted and at a lot lower price.
