Same as Bozzer for me too my First national shoots and i thought they were both great courses and had no complaints at all (bar some of my own silly mistakes) Both courses had there tricky and cheeky targets that made you change position, but isnt that what HFT is about, if it were easy we would all clear the courses and then moan about that too then.
If there is a hump in the way of a target move so you can see it as bozzer said about the drain pipe with nails through it at rivi on the left of the peg you had the nails cris crossed in the way but by just moving over to the right of the peg i had a clear shot.
