Fly Tying General Discussions / hard water vs soft water maybe?
« on: January 04, 2019, 08:21:27 AM »
So I've been experimenting with CDC dry flies and since everything is frozen I usually just throw them in a bowl of water instead of testing in the field.

I was happy with the results and decided I would tie a small army of these over the holiday at my parent's house.  I tied about 25 and one night decided to throw 5 is a glass of water. 

Within 5 minutes only one fly remained at the surface. Dejected I put my army aside hoping applying floatant back home and retesting would salvage my efforts.  I flew back home and when came testing time I decided to test the same 5 flies with no floatant again.  All 5 floated over night.  Shaking the bowl of water to cause waves would not bring the flies down.

Maybe this is all in my head but I'm very curious as to what happened.  The water is noticeably harder at my parents' house; emptying and entire bottle of shampoo on your head will results in just about no foam.  Perhaps there are some ppl here with studies in particular field that could explain this. 

Only three things changed in my experiments:  Soft vs hard water, bowl vs glass; my parents have a wine cellar and I don't ;)

Does anybody have a good Entomology book to suggest.  I'm stating to take interest in these critters at my feet and on my hat.

Fly Fishing General Discussions / Fishing shades.
« on: November 23, 2017, 07:28:54 PM »
It's really hard to find your 300$ Oakley's in the water at your feet once you don't have them and their polarized qualities in front of your eyes. And so off they went into the current as my client yelled: "They're right there, right in front of you!"  He still had his shades on.

I see high end sunglasses as a lifetime investment and treat them that way. Last thing I put on before entering the river. Out of the case; onto my face. First thing i take off when i get out; back into the case they go.

It's black Friday and I'm in the market for high end shades, or at least I thought I was until my gfriend came home to share the news that the optometrist said her 700$ prescription sun glasses should be changed. Not because of the scratches that come with stuffing them in her purse.  But simply because; they are to old.

Excuse me? 700$ shades wear out? I call BS and I'm going to prove this to be some gimmick to get your insurance company to buy you new glasses.  And so off to the google machine I marched.

Lets break down fishing glasses properties into three important components.
Polarization - blocks glare (that's the last we'll speak of it)
Tint  - blocks visible light, ideally with a contrast appropriate for the color of the river bottom.
UV Protection - blocks none visible light (damaging light, think cancer)

Here is the kicker.  The UV protection barrier deteriorates over time. As much as 20% over two years. Tint does not.

So 4 years down the line you put your shades on and the tint does it job and blocks visible light.  In turn your eyes do their thing and dilate, they open up and let in as much light as they can. Mean while your UV protection is way down. You're eyes don't know that, UV rays are none visible light.

You're frying your eyes and you don't know it, don't feel it.  Your old shades are tricking your eyes into exposing themselves to some pretty harsh UV rays.

Most of you own a UV flash light and some UV sensitive tying material.  Find a dark room, take all your sunglasses in there with you and test them.  Shine the UV flashlight through the lens at the UV sensitive material.

My brand new 30$ Berkley outperform my 5 year old 200$ RayBan, and my 7++ year old Columbia, by A LOT.

I'm no longer in the market for the high end stuff.  I'm going to keep rolling the 30$ stuff and try all sorts of different colors under different conditions.

If you don't have the equipment to test your shades, then go to Brazil.  They've tried to deal with this issue by offering self serving analysis kiosk:

Fly Tying General Discussions / Ants eating fly tying material.
« on: April 28, 2017, 06:11:42 PM »
Will ants get at your fly tying material?

I've moved everything to a secretary desk and the compartments aren't exactly sealed shut.  Been seeing ants on the desk.

Stillwater Fly Fishing / Swim bladder adjustment.
« on: March 27, 2017, 08:34:06 AM »
Finding at what depth the fish are takes some work.

Once they are found how likely are they to change depth? 

Is adjusting their swim bladder physically demanding for them?  Is it something they avoid doing to often?

Is it easier to go up than it is to go down?

I can't find any interesting scientific article covering this subject.

Fly Fishing Product Reviews / HMH Spartan.
« on: February 17, 2017, 10:30:04 AM »
Hi,

The pin on my vise broke. I was rather disappointed and following a friend's advice who assured me HMH was a good company; I decided to contact HMH. Here was their response the very same day:

"Send me your address and I will replace the pin.  If that does not work, send me the cam lever and I will fit the pin or replace the cam lever."

That's it, that's all.  No questions asked.  Just a company standing by their product.  I was very impressed with this and wanted to share with others.

Also, it's a great vise:

I know where my money is going next time I need to buy fly tying equipment.

Cheers.
