Iain,
I've lost count of the flies I've lost - all in the following manner...............
When I'm tackling up I'll select three flies and either;
* keep them in my hand as I proceed to tie them on one at a time - by the time I come to tie on the last fly (and sometimes the second) I find my hand is empty! DOH!
* Place the second and third flies by a very distinct leaf or blade of grass on the ground - again after I tie the first or second fly on I can't recall which blade of grass or the leaf has blown away!
* Place the second and third flies on my bag or hooked slightly into some garment or other - you've guessed it when I go to tie it on its gone and I spend 5 min's looking for something small and green in a field of small and green.
I know there are fly patches around & I have one inside my chest pack but I have my stupid ways and I'm too lazy to open my chest pack flap as I know what I'm doing - I'm a professional
Anyway I've solved the problem and field tested it last Monday - I bought two of those clip on Orvis magnetic single zingers and they are the biz.
sorry to bore you but I must have lost 40-50 flies over the last few years this way.
Iain
