So, I saw a posting of a fly called 'Landon Mayer's mini-leach' - which is basically a very small zonker tied on a curved hook.
REALLY simple, takes no time to tie and looks the business:
- Grub or similar curved hook ( can be tied easily on a 12 or 14)
- tinsel body
- pine squirrel or mink strip ( which I used)
- ostrich herl
