Mary, thanks for sharing your routes. sitting at my desk it took me awhile to figure out how I would attack #8 as I always have difficulty in green marshy areas. Probably would have tried getting that large cliff north of your control (other side of the marsh for an attack point.
That's what I did. Even when my husband passed me at the first big cliff, I stuck with my plan to attack from the next one and found #8 easily.
