Rotation-translation diagram / Sinking lines / Testing leaders

Walter & Group...

I dug out Bruce Richards' diagrams on Rotation, Translation, Combined Rot.& Trans. plus drift.  Hopefully this will help answer Jerry Puckett's question.

                                                          FISHING SINKING LINES

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I asked Bruce Richards for a run down on the development of modern sinking fly lines.  This is what he sends us:

Hi Gordy, happy to help.

I don't have access to my work files anymore so can't give exact dates, but density compensated (we call "uniform sink") lines were developed first by SA sometime in the early to mid 80's. AirFlo has claimed that they first made DC lines, but we were selling them before AirFlo even existed. I first made DC lines to solve a fishing problem I had. I often fished a walk-in, catch and release lake for big bluegills. In mid-summer the fish were deep and hard to catch and would only eat a very slow moving rubber legged spider. Conventional sinking lines didn't fish straight when retrieved slowly, the bellies sank faster than the tip so the line always had a belly in it. That belly was essentially slack line which masked the subtle strikes. At that time we made sinking tip lines, lines with sinking tips and floating bellies. I thought that if I made some lines with sinking tips, and slightly slower sinking bellies the lines should fish much straighter and be more sensitive to the strike. It took a while to get the difference in sink rates right to optimize performance, but once that was figured out, the lines worked very well... Now we make them in a more sophisticated way, blending coatings of different densities to fine tune the sink rate through the line.

 

The sink rate number rating system is mostly a marketing tool right now, there is no industry standard. One companies "type 8" line sinks at the same rate as anothers "type 6". Simply putting a higher number on a line will boost sales. I've proposed to the industry that we standardize the system. There is general agreeement that we should, but it appears it will be up to me to get it done. Now that I'm retired, I might even have time! What I think would work best is a system where the sink rate number relates directly to the sink rate of the line in inches/sec. This is what it would look like:

Type 1 - .5-1.5 ips

Type 2 - 1.5-2.5 ips

Type 3 - 2.5-3.5 ips

etc.

The reason for the range is that all lines made with the same coating don't sink at the same rate. For a variety of reasons, a 4 w. sinking line will sink more slowly than a 9 wt. sinking line made with the same coating. Allowing a range would make it easier for line makers to manufacture the lines and control cost/price.

 

Let me know if you need more info. Gordy....

From Walter Simberski:

Gordy - now for the exception to the rule - fishing boobies for trout. These flies are very bouyant but

are fished with full sinking lines (preferably density compensated). During the retrieve the angler alternately

strips and then pauses causing the boobie to bob up and down as it retrieved. The overall effect is that

of an injured critter swimming through the water.

 

In general, I find that when fishing with sinking lines a short leader (3 feet and less) gives the best presentation

and control. Again there is an exception here - when fishing with clear intermediate sinking lines and moderately

weighted flies I find that a longer leader (7 - 9 feet) seems to work best.

Walter...    The Boobie is a new one on me !!!

 

I use the same basic principle, however, often when fishing poppers.  Trick is to use an intermediate sink line.  When you make an erratic retrieve, with each pull the popper makes a "pop" or a "chug" (depending upon its design) then immediately is pulled under water for a moment leaving a trail of bubbles which really turns some fish on.  By using the sinking line, its less likely that the fish will push the popper fly out of his own way with his "bow wave" as he tries to get it.

On teaching with a sinking head by Peter Morse:

 

Gordy and group, For the first time I recently used a shooting head to 
teach the double haul as per Mel Krieger and more lately Eric Shearer. 
It was very effective BUT I found myself dealing with endless 
questions about using shooting heads rather than focusing on the haul. 
I was a little time restricted and although I'd given them a good 
explanation of what we were doing and why we were doing it this way, 
the distraction the shooting head created  detracted from the double 
hauling lesson. Mind you they all threw the thing further than they'd 
ever thrown a line before and were pretty happy about that. I guess 
they left with something new but I would have liked their hauling 
lesson to not be so distracted.  Perhaps an integrated shooting head 
would create less interest in the "tool" itself and more focus on what 
we were trying to achieve.

 

This is relevant to my earlier email (on the carpenters ) and upon 
reflection I've put in a concluding sentence:

 

A name for this action could be "Hammer Hand" - when we want 
"Painter's Hand" - or for the Lothario's and poets  "Lover's Hand".

Peter...   The integrated head might indeed generate less banter.

 

Tom White used a length of heavy monofilament nylon for this purpose ..... worked well.

 

I like your wordsmithing !

                                                MORE ON TESTING LEADERS

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

Bill Kessler figures out a way to solve his own problem ..... recoil when purposely breaking leaders while testing.

G.

 

Thanks, 

I've been using a Chatillion,  I just need to change how I attach my leaders to reduce the recoil in my direction.  I just realized if I attach the scale to the bench and pull on the knot in the other direction that the scale will pull away from me on the break, sometimes the simple solution is the best even if it takes awhile to figure it out.

I appreciate all of your help.
