I have had more hits with a sparser parachute hackle. been trying to get by with max of 3 turns. but it feels so easy to put 5, or maybe 6 turns in. I am susceptible to the more is better trap.
My unconfirmed suspicion is that it hangs lower in the film. I'll be sticking with that for the time being.
The Klink seems to look better with a thin tight body (not unique in my view, but thats off topic) but I havent noticed any increase in hits with the tapered quill type bodies. And since the dubbing is easier, I tend to go that way.
Where I fish, yours will catch.
