During summer season I cast a lot of topwater flies.
Deer hair divers are favorite and add a great fun to your fly fishing.
I've got some variations of them.. with the splayed out feathers, long synthetic fibers and with a bunny tail as well.
The hides of those bunny strips seems to have a lot of stretch in them.. It seems this inhibits the diving capability. (Just a thought.)
The hides of finn racoon zonkers strips have less stretch, so there you go..
About a piece of 3 inch will do and have just the right movement you are looking for.
By the way.. if you're looking for a new very good deer hair packer, I can highly recommend ya this one: SF Fugly Packer
A new type of Pike fly i've been working on lately.
Uses: Flex Tube XL (Tail and Prey fish.)
DNA holo fusion and some long rooster saddles on top.
Some fur as chin and end tail.
Much of the hookshank been kept clear, to keep some space for the prey fish.
I've only used some mylar cord to decorate it.
