A couple weeks ago I was asking if anyone had this information. For those interested in UL spinning blanks, here is the data for the Rainshadow IP840 and St. Croix 3S70ULM2 blanks I just received yesterday.

Rainshadow IP840 ERN = 8.03 AA = 70

St. Croix 3S70ULM2 ERN = 5.35 AA = 67

I will post the data in the CCS database too. I'm going to build them both with graphite tubing TN grips, then BYAG 20, BYAG 10, BLAG6s out to BFAT6 tip. Should be a pair of very fun rods.

The super fast action of the Rainshadow model intrigues me. I assume it's a 7 footer?


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

Yes, 7' 1pc. I think that given your passion for light line smallmouth fishing, it might be one you want to look at. The St. Croix model is a 2pc.

I have a question concerning the CCS, and mesurring the ERN. Does a cent weigh only 1grain? It seems kinda 2 little, since a grain is about 0,06g. I'd like to be able to mesure more than the SS of a rod, but for that i'd need to know the actual weigh of an american cent.

And another q regarding the mesurement of the ERN...it says the rod should be bent to 1/3 of it's actual length? Why is that....shouldn't that be determined by the AA? If it's afast rod...bend it 2 1/3 of it's actual length, if it's a mod/fast rod....bend it 2 i guess 5/6 of it's length or about that, cause the slower the rod, the more it'll bend when u actually throw something. Shouldn't that be taken in consideration? I'm sorry for doubting the ERN mesurement, but i'm learning to be an enginere, so it's kinda natural to pose these questions.

Sorry for the bit of the off topic!

The IP841 I built was also a fast tipped rod, a little lighter powered version of the Loomis P8400 or Shikari P7000 blanks.

Andrei, the weight of a U.S. penny (cent) of modern manufacture ('96 and since) is 2.50 grams.

To measure the ERN and AA of a blank, you have to use the exact methods Dr. Hanneman specified or else you can't compare your results to anyone else's. Using the exact methods is what makes the system a standard. Like using a meter stick that is exactly 1 meter. Otherwise, everyone's data would be different and we would be right where we started, with arbitrary definitions of power and action. Sounds like you better read the articles before you do this or you are not going to get the right results. A good place to start is the link at the top left, "common cents info."

Andrei,
I think a cent weighs 3.33 grains if I remember right. It's in the Common Cents Info site to the left for the correct info.

I've been corrected, thanks Steve. I need some coffee I guess to wake up what left of the brain cells, the wife says I'm getting more AllTheTimers everyday. Just came back from my annual Alaska trip and I still remember that I can't stay there all summer so I guess it's not to bad yet.

Andrei,

You really need to read up on the CCS. The deflection amount is a standard - if you use different deflection amounts the data won't be relative across the board. Also, you needn't worry what a cent weighs - the author has done all that work for you and offers the Rosetta Stone chart for the conversion to ERN so that all you have to do is just count up the number of pennies needed to obtain the required deflection and then relate that to the power chart.

Dr. Hanneman has recently released the "Universal Rod Rating System" and it will appear in the Volume 10 #4 issue of RodMaker Magazine. This is simply an expansion of the CCS so the new Rosetta Stone chart will include amounts that allow you to measure and compare the heavier spinning and casting rods as well.

The IP840 is a very overlooked "Sleeper". Builders that are looking for a * 7 ft., One-Piece* blank that is sorta in-between a light and ultra light, the IP840 is a fantastic blank and the price is right. But, for some reason this blank just is not getting the attention it deserves. It is very versatile, with the light tip and still enough butt power if you do happen to land into a larger fish. For me, it makes a great panfish, crappie, trout and smaller bass rod. Just a super fun rod !!

Bob's description of the IP840 sounds dead-on and I can't wait to get this thing built. Got two trips in the next two weeks and both these rods are going with me. He's right about the price - $34. I've heard several people ask about short bass fly rods on the board before. This is a great candidate for that. My IP840 will have a TN grip so I can easily put a fly reel and a 7 or 8wt. line on it to throw big bass bugs.

Thank you guys for the replyes. I've read the first article before posing these q's didn't have time to read the other ones, but making time for them as well. I needed to know tha weigh of a cent so i can d the ERN wit regular weights, mesure, and divide by the weigh of a cent.

Steve - thanks for the information. You (and Bob) answered a question that's been rambling through my mind. I've been thinking about a short, heavier weight fly rod for river bass fishing, and in particular for our Shoal Bass. I need to chuck and duck big, heavy streamers directly into shoals while wading. Distance isn't an issue, but having power and leverage to quickly turn the fish before they bull dogs back into a cave is. It sounds like the IP840 would fit the bill. Also like you idea of setting it up with the TN as a combo (just in case I have to go over to the darkside and throw a spinnerbait :) ).

Glad to help a brother out. I fish a lot of small water with big flies so I think these two rods will both get used alternately as spin and fly rods. Most of the water I fish can be very well and effectively covered with 20-40 casts and stripping streamers or chugging poppers. A long rod is just not needed for that type of fishing. I don't like to wade with a net and I am short (5'6") so I find landing and releasing fish a lot easier with a relatively short rod. My short reach makes that task with a 9' rod sort of a pain in the butt.
