Interesting article on mastering the whip finish by Magnus in this issue of FF&FT.
Must confess that fly tying is not my forte and I usually fish with flies kindly made by friends. I do dabble, and used to tie flies back in the Haddo days, these fished very well and caught their fair share of fish. But - I've always been a tad lazy and finished with a few half hitches.
Perhaps the time has come to get myself a whip-finishing tool and put in a bit of practice!
