The centre rippling is "wavery", other than that its a good opening, all three furrows are the same size and its cut out very cleanly. A tail fin on the front coming back may have smoothed the slice a little but its very easy to press too hard, and when you stop looking, the slice sticks, and you have a heap of narrow stair carpet in the plough! looking again the centre rippling could have been a little more central, though I think there would be enough of it to support the front furrow of the second crown runwhat's wrong with this one then Harry? Are you saying that the back furrow on the second run is too far to the left? Enlighten us please.
