Rod Action/Grain Weight

So I have 2 rods I'm trying to get figured.

The grain window for one is 190-270....this rod is a full flex action
The other has a range 300-390....this rod would be a mid flex action

My question for the experienced is...Does the action of the rod help determine which way to go in the "grain window" range.

ie. a full flex action rod would be better served by the lower end of the grain window

ie. a mid flex action rod leans towards the higher grain end of the window

My local sporting goods stores do not have ANY spey/skagit/scandi lines so I am forced to order online.Testing various grains/lines is not an option for me.

Please share with me your various opinions to help make my inevitable online purchase a correct one.Returns/exchanges through the mail are a pain in the !

Thank-you Kindly

There are a number of factors that may affect the selection of a line within a rods grain window:
Type of fly line - Typically skagit and traditional spey lines will be towards the higher end of the grain window whilst shooting heads will be middle to lower end of the grain window.
Type of spey cast - Touch and go casts like a single spey would generally be better with a line lower in the grain window with water bourne casts like a snap t or double spey better with lines higher in the grain window.
Casting style - Do you cast more with the top hand, with both hands evenly, or more with the bottom hand. Do you use a short stroke or a longer stroke length. Do you like to hit the rod or do you have a more relaxed casting style.
Casting skill - Both fast action and full flex or through action rods require more casting skill. A fast action rod requires better timing but is more forgiving of poor power application. A through action rod is more forgiving in terms of timing but requires good power application. A mid to tip rod is probably the best all round rod especially for a less experienced caster.
Personal preference - Some people like to cast off the tip off the rod and would typically use a lighter line than people who like a deep load.

Do not confuse a rods recovery speed with its action as they are two different things.

Personally I like mid to tip action rods, that bend nicely into the blank and have a fast recovery, as they are more forgiving in real fishing situations when I am deep wading or have restricted casting room. Full action rods are great with plenty of casting room but I struggle with them when under pressure. I also like to hit the rod a bit and do not have what might be know as a relaxed casting stroke. I generally fish with shooting heads in the lower to middle end of the grain window and skagit/traditional spey lines in the middle to upper end of the grain window.

All rod actions will cast all types of lines anywhere within the grain window, and probably some outside the grain window, depending on caster skill and preference, but some will be better suited to certain lines types and/or casting skill/style.

Hope this helps.

As Darren pointed out the line type and weight has more input into casting than an assumed rod flex point, which can change greatly with different loads and casting style.

Below is Meister Meiser's excellent explanation of Grain Windows.

Contact Poppy at the Red Shed as he may be able to help with some test lines.

I vote No.
Read up on grains window at Rob Meiser Rods fro a clear explanation of how grain-windows are determined and how an angler can use it as a reference.

It was first recommended to me that I over-line by one weight class then to back-off again once I got the feel for the rod/load. I was totally clueless of all the specifics being thrown at me but the grains window and the line-weight classes where helpful in determining just how much I was over-linning. Then again when selecting a new rod I would dedicate to casting skagit-heads in winters I referred back to Meiser's take on grains-window to pick out the rod-weight and lines based on what I already knew from casting other types of lines. Looking through the window from a-ways back has worked well for me. Apparently - others have found it useful in determining where a specified taper should weight-in the window.

just a thought that more full flexing rods lend them selves to casting of the tip or casting all the way through the butt which gives you a pretty wide grain window

I have the 12' 2/3 wt Anglers Roost that is full flex and it will pretty easily cast off the tip with around 240 grains or less but will easily handle deeper loads up in the neighborhood of 330 to 360 grains or even more
