I've started using spiral rods or acid rod and I'm loving it. It cast well and I could go for less ring guides which makes it lighter.

Here are some reasons to go for Acid rod:

Spiral wraps make it less torque on the rod when fighting heavy fish..

This way you can have a lighter rod for heavy application. Casting distance is about the same conventional rod. The spiral prevents the line from touching the blank with less guide compared to a conventional since the guide is already pointing downwards. This results in a rod which will not twist under load and is inherently stable."

Anyone else tried using it?

I've heard of many of the positives of spiral wrapped rods, and agree that it has many merits, BUT I just can't bring myself to build one.  It just looks wrong to me.   :-/

I built most of my rods most of them are spiral wrapped.  I've used several spiral schemes incl O'Quinn and Forhan but my favorite is using just one bumper guide to get the line from the #1 UP guide to the #3 DOWN guide.  Casts just a well, simpler to lay out and wrap, less opportunity for guide damage.
