Gotta match the hatch.
 
To give yourself a chance for creativity and not be bored.
 
My wheat head flies were tied on #6 Mustad 9672 hooks to match the length of the grain.
It really did make a difference. 
 
I'm still waiting for a reason a 1/0 is needed.

OK, I missed the wheat head part of it. I was just thinking dough balls. I was real good at matching the corn hatch as kid in my local ponds :)

Since no one else will speak up about the 1/0 hook, I will say the only benefit you'd get out of it is a higher positive hook up after a strike and head turn given the wider gap... especially with a turned eye octopus hook with a Snell knot.

On the lower river chrome slobs in early salmon season I usually use a number 4 Edward seely turned eye octopus... years back we got a deal on them by the thousands along with number 2's... in higher water I use the 2's as the 4's brake from time to time with heavier tippet. A 2 is a little big for my likings but I use what I have. I think I we got them for well under a penny a piece and still have a few thousand of them. The 4 is a nice one..I think tuna saw them hanging At my place a year ago or so.... it seems smaller than a typical 4 and compliments a lower river early season egg pattern quite nicely and holds a skein looped with a Snell knot very well. When the fish turns after a strike, the hook drives

hot tuna
or... Just wrap a 1/0 in wonder bread..

But what would the fly snobs of the world think of that???? Lol

Well truth be told I dont use a 1/0 , just some chitty tied fly..   Ain't no Orvis shop out behind my house so who cares ..lol
 
 

Have a few #1 popsicles in the box that I started with but now use the 4s early on. Once in a while a 2 if they are feisty.

Two Bob I scent you a pic of my #2 and #4 Edward Seeley octopus hooks next to a #6 eagle claw razor sharp. Surprisingly the #6 is bigger in eagle claw. It would be interesting to see chartists 1/0 next to another hook as a comparison

That is why I asked for a pic of the fly next to a quarter.
Then I could see why such a big gap was needed.
The question arouse because he said he fished 6s for steel but 1/0s for salmon.
Why the difference?
It's why I showed one of mine next to a quarter to show you can have a pretty darn big fly without having a hugh hook gap.
Or is the hook gap the important feature?
If you know what I mean?

Last summer I bought maybe 200 flies for the upcoming salmon season.  I wasn't sure what would work...This was only my third season of salmon fishing, so still learning.  I bought these 1/0 estaz eggs from a tier on ebay....They worked.  Most of the other salmon flies I bought are probably number 2 hooks.

........

I release all the salmon I catch.  I just enjoy the battle. 

Out of 200 flies you don't have 1 left you can take a pic of next to a quarter?
