There has been a TON of talk about the ACID WRAP.
i will try to help explain..

here is the main info.

The spiral guide placement was first patented in 1909 by John Scanlan of Chicago. It was made popular by Chuck Roberts, who ran a custom tackle store in Kansas City, Kansas, in the late 1970's. The spiral wrap was referred to as the "Robert's Wrap" by another famous rod builder, Joy Dunlap, and the name stuck. Controversy still surrounds the exact origin of this guide placement method.

For Our uses we use a few different methods of "spirial".

The Newest spirial The NZ style came about after Jim from EASTERN TACKLE, had a spirial rod done by JPR RODS, View attachment 12161 ,and wrapped to the right

they were doing a double stripper spirial guide wrap in newzealand which seemed to help with "line lay".

we tried the same method, and to keep my rods identified. i used NZ in my model write up, such as JPR NZ STYLE..you will see them often on the web. View attachment 12159

Other "spirial" methods .

There are a few other way of spirial in addition to the NZ which is the newest, for me..

You can start with the stripper guide on top, wrapping to either side, with the spirial.
some guys use 2 guides going around some use 3, personal prefrence.
I prefer 2 guides .

NEXT

You can start with the first guide "slightly" off center,
this setup is what my first acid rod was.
it was made for me by a guy from california.Jim AKUHEAD who started the term "acid".
they are nice, but the line goes to one side...it wasnt my liking.

NEXT
you can do a "bumper" method.
starting with a guide on top,
and then one SMALL guide at a 90degree, followed by the 3rd guide on bottom.
typically the "bumper" is small guide..
I Really dont like this.

NEXT

The regular sprial.
starting with a guide on top of the blank,
i use a 2 guide transition. typicall to the left..it really doesnt matter which way..left is MY way.

There are a few Other spirial options.
these are the most popular for me.
some we use some we dont.

they can be used for trout to tuna,

we are still testing, and getting good feedback.

i hope this helps

basically when the line is wrapped conventionally with the guides "on top" of the rod,
when pressure is applied. such as fighting a fish.

the line will be trying to get under the blank, putting force on the guides, that will lead to twist and torque of the blank, when under pressure.

when rods are wrapped spirial there is no torque or twisting of the blank.

Paul,
The way I remember Jim telling the story was he took a spiral wrapped rods on one of the CA headboats where he was asked a bunch of "why it you do that" questions. One of the deckhands looked at the rod and said he must have been on ACID when he wrapped it and the name stuck...

great effort Paul

the only comment I would make is in reference to :-

"when rods are wrapped spiral there is no torque or twisting of the blank."

Its a fine point, but it is more correctly stated as " there is negligible twisting of the blank".
There is radial torque in the transition section of a spiral under load .
The key point is that it is low relative to the blank rigidity in that section of the blank ,and it doesn't generate twist in the blank.
Similarly the tip section of the rod has low rigidity ( by design ) and placement of the guides under the blank minimises twist in that area , relative to guides on top of the blank when under load.
The highest torque potential ( from the guidetrain ) is at the tip .
Having the tip and adjacent guides under the rod rather than on top of the rod mitigates rod "twist" and assists rod stability under load.
Having guides under the rod in the majority of the deflected section of the rod , under load, makes the rod more effort efficient.
ie
the angler has to pull less to get the same pressure on a fish relative to a rod with guides on top.

This is in reality the biggest advantage to an angler in the "Roberts Wrap" / "Acid Wrap" spiral guidetrain design................whether the angler realises that is another matter .

I prefer to get the line to the underside quickly for less opportunity of any type of rod torque.
When the guides are properly placed line flows though quite smoothly applying little if any pressure on the rod.
This is my way and I guess we all have our preferences in regards to these builds.
