Hello all. I have a question. Carrot stick wild green rod is built with a dual helical bias rod blank. What rod blank that i can purchase is comprable or exactly built that way?

can you explain what a dual helical bias is?

Warning....this is my opinion and someone please step in if I am way off.

It sounds like a play on words.... Helical is spiral wrapped, and when something is cut on a bias it is diagonal....sounds like two of the same thing to me. Aren't a lot (or most) blanks now a days wrapped in a spiral configuration? I think the over looked thing that they advertise about their rods is the multi modulas similar to the MHX blends.

This is what i found on dual helix process. I just wanna lnow what rod is close to it so i can buy one. I would rather build my own. Dual Helix Facts
United Composites-USA's "Dual Helix" ply construction produces a rod blank that has outstanding resistance to both crushing and twisting when compared to the competition.
United Composites USA's unique construction technique, adapted from our experience in aerospace activities, is superior to the conventional rod blank roll-wrap manufacturing process adopted years ago from the textile industry.
Two advantages are readily apparent.
The Dual Helix structure keeps the rod round when heavily loaded during casting or fighting a hooked fish. When conventional blanks are subjected to heavy bending loads, they have a natural tendency to start to go oval because they lack helical reinforcement designed to resist these loads. A rod that starts to become oval is no longer as stiff as it was when round and will fail by buckling if the line pressure is not backed off. This problem does not occur with United Composites-USA's Dual Helix reinforced blanks. In addition to the phenomenal bending strength the Dual Helix construction adds extraordinary crush and nick resistance, making United Composites USA's blanks the most durable on the market today.
United Composites USA's second major advantage is the outstanding resistance to twist imparted to the blank through the Dual Helix design. When casting there are sidewise loads introduced when the fly line is moved out of the fore and aft vertical plane by winds or casting actions. These side loads during fore and aft casts will twist the guides of a rod that does not have the Dual Helix resistance to twist. This twisting deflection is not recovered in the fore and aft casting stroke as casting energy but is lost. Torque loads from twisting rods account for much of the casting arm discomfort and lack of precise fly line directional control.
The term helical is starting to appear in ads from other rod companies, but United Composites-USA's Dual Helix construction is unique and we have used the proven technique for over twenty years.

United Composites/GUSA, there are some downsides to this construction. Bias graphite loses a bit of modulus over linear graphite construction and they can be a bit heavier. Greater possible durability is a plus due to greater hoop strength.
GUSA used to have blanks to walk on at their booths, pics of fullsize 80's Bronco on a blank without crushing it.

GUSA built very high quality blanks which were also known for their tremendous durability. Part of that was due to the dual helix construction and part of it was due to the small diameter heavy wall design.

Whether or not the Carrot Stix dual helix construction is similar or even true is beyond me.

Some thing like the Herculis blanks

sounds like the old Cortland woven rod blanks to me. Had two of them break just testing (carefully) the flex. Have never had another rod blank do that.

Over the years there have been a few of these "dual helix" blanks. They tend to be rugged and strong but also weigh more. I have an old Kunnan rod that was made like that.

United Composites and American tackle are two that offer them today.

I have a 50-year-old, white, 7'6" fiberglass Shakespeare Wonder Rod four weight. I believe it exhibits a "dual helix" blank construction - but the flacks back in those days called it the Howland process, or something like that.

Not the same thing.

Dick Kanter developed brought this method to rod building in the late `80's and Fenwick had a line of single Helix blanks for a time but they never sold well. Dick then started Graphite USA and made the now well known GUSA blanks. Stephen Pratt of CTS uses this method on some of his line of NZ based blanks and was trained by Dick on how to do it. It basicly has been used by gold shaft manufactuers as well.

All it really is a unidirectional carbon layed up in a wrap around method + or - 45 degrees. It also uses traditional cloth patten layups in conjunction with it. Biased and helix is really the same thing. All it is, is another method of making a rod blank nothing more. Some claim it's better some say it's no different.

the Shakespere uses the Howald process and is nothing like Helix or standard cloth layup process. Howald is all machine done with glass and or carbon strands wound on reels and wound onto the mandral after the thread passes through a resin bath.

I'm no expert on this issue, but I do have a pretty sensitive @#$%& detector, and it just went off. How many of the problems that the process is supposed to solve have you experienced with blanks made with other processes? I have had none. All of my very few rod failures have been because I did something stupid with the rod, and I really don't think any blank build process would have prevented them.
