A big shoal of red herrings contributed to a very decent challenge... and Shy threw me ;-)

Shy was difficult for me as well, but I got it through elimination eventually. A really fun challenge!

4/10..one more if my incorrect but valid reason for the Throw line (can all precede the word out) counted

Urbanbaboon. You're right about "out" following the "throw" group of course. So many verbs can be followed by "up", "off", "back" etc. I try to avoid such connections and didn't include "over" as a prefix meaning "too much" for the same reason. After all, this is The Wall not The Weakest Link.

5/10 for me. I fell into the same trap as the baboon. Thanks for the testing grid.
