Have to say yeah, but no, but yeah, but no but well..depends on what I am fishing with!
Big flies for Pike/Perch/In the sea I use a keeper ring as the leader is normally sub 9 foot.
If fishing for trout, I have to say I tend to hold the point fly between my fingers and leave a bow in the line, so upon arriving at the next swim, its just a case of a flick and I am fishing again.
Once more, habit!
