Check this, it's my own invention but probably been done a 100 times before.
Taught me a lesson last saturday did that fly. I went fishing on the Lugg at Mortimers Cross with young Spencer. First six casts resulted in four fine wbt, which were natch released quickly without fuss. Then in my excitement I launched it up a distant tree and there it remained. I did not have another in my box DOH! Never again will I fish a fly if there is no back up in my box, what a silly thing to do

. Needless to say sport was patchy for the rest of the day
