Troth's Zonker is really an easy pattern. This is it:
1) Hook: 4xl to 8xl streamer hook with a straight eye
2) Underbody: either aluminum or lead tape over the hook then doubled on the bottom and cut so it
tapers from hook shank at rear to a hook gap 1/4 back from front of body and then
tapered again from this point to the hook shank. This produces the nice deep belly and
tapered body of Troth's Zonker.
3)Body: Silver, gold, or pearl braided mylar tubing with thread core removed of appropriate size
for the hook. Shred (separate) the reat of the tubing with your bodkin before slipping it
over the hook and aluminum or lead tape. Body is tied down at rear with red Danville's
Flat-waxed Nylon (use a bobbin, tie it in on the hook shank by pulling the body forward).
Don't forget to let the shredded portion extend over the hook bend. After it is tied in at
the rear, let the bobbin hang, you will use it to tie off the rabbit strip wing. Then tie in
front of the body with black thread (Troth uses 3/0 Danville's, but any will work).
4) Hackle: Grizzly (natural or dyed to match or compliment wing), sparse and webby.
5) Wing: Rabbit strip 1.5 x's hook shank in length. Tie it in at front by first clipping it to a triangle
shaped point to reduce bulk at the had. Whip finish this before tying it in at the rear,
where the other bobbin should still be hanging with the red Flat-waxed Nylon. Slightly
wet the rabbit fur where it will be tied in at the rear, separate the hair, and tie it in with
the red Flat-waxed Nylon. Then use a loop of thread to form a whip finish of 6-8 turns
right at the rear tie in point.
Sometimes Troth puts eyes on them by tying in a set of flat plastic eye that have the plastic tabs on them, but his is optional.
If you follow the above pattern in order, you will be able to tie any color Zonker you may ever wish to tie and have them look like Troth's. They are really very easy to tie, which you will find out after you tie your first one.
Or sub in foam under body for the lead or foil under body for the floating zonker. The floating zonker works great for bass and trout and can be worked like a Rapala on the surface for some really fun surface strikes or just off the bottom of a lake or river and a sink tip line with the foam helping to keep the hook just off the bottom snags.
