Will do. Thanks for the tip.

Not for Nothing
But
Where did you get these blanks and who made them If the weights are put into onces they relate to 18 plus onces of lure weight

Bill,
The 18+ oz is required to achieve the CCS deflection of the blank (this would be the tip deflecting downward a distance equal to 1/3 the length of the rod blank.) The lure or fly line weight required to comfortably cast the blank wold be significantly less. My guess wold be somewhere between 800 and 900 grains, but who knows, it's quite a stick by the numbers.

I was just curious to see how much it was in onces Got a nice site to just put the numbers in It does all the work
Geoff
What will that relate to as line size ?

It would be interesting to hear others run a CCS on a 14-15" spey rod or blank and see what it takes to deflect the blank a 1/3 of its lenght.
My three rods are from different makers. It seems far fetched that all three would suffer the "broomstick syndrom ". Just saying....
I've added the guides today so maybe I get a chance to do some tests with different lines tomorrow.

I don't think they're out of line as is. But if you want to use the ERN or Intrinsic Power to relate to a line weight, then you'll need to use a different factor than you might use for a regular single handed fly rod. Not a big deal, really.

.........................

From my personal experience I would say that if you were to use ERN to select starting point line weights for spey and switch rods, ERN-2 would be good for switch and ERN-4 for spey lines. This of course would be applied to the numbers on switch and spey products (if they have line numbers listed at all) and not to single handed lines. This non-correlation to single handed fly line weights is likely the reason many switch and spey lines and rods simply use actual grain weights vs. line weight numbers. This is really nice to see actually due to the objective nature of grain windows.

According to my calculations the rod will not be a broomstick and should adequately cast a 9 - 10 weight line.
This lies within one line weight from advertised. Certainly acceptable.
Perhaps the CCS has a problem with the conversion ?

Gene

Geoff and Eugene: thanks a lot for your input. Maybe the CCS need some conversion factor as mentioned.
Eugene, can you please elaborate a bit how this rod would fit a 9-10 weight line? Would be very interesting to hear more.
And Geoff, any more info to be found about ERN-2 and -4 for switch and spey rods?
Thanks in advance.
Göran.

Göran,
I've created my own spreadsheet to determine rod casting weight.
The specs you gave allowed me to run a stiffness test on the rod taper to determine casting weight based on fly lines specs.
This blank should possess a slow butt with a light fast tip section. The tip section primarily determines the proper line weight while the butt determines the rod's ability to control the tip.
In addition the rod blank should weigh approximately 5 ounces.
The calculation is made based on an IM7 blank material and measures taper proportions over the blank length and compared to an existing blank with known characteristics.

Gene

Mr. Sandberg,
I don't think you'd find too much more info as that is only my estimation based on my own experience. This estimation is actually quite useless, as so many of the double handed lines and rods carry grain weights or ratings and no line numbers. As I said before, its a good thing in my opinion. What would be nice is to have enough data samples to build correlation between a comfortable (or good starting point) double handed line weight and the CCS intrinsic power in grams, or ERN. Outside of single handed fly rods I don't calculate ERN. I would rather build my frame of reverence around the raw weight required to deflect to CCS specs. Just my personal preference.
