Part 2 - What’s EVO? The evolution of TMC Ceramic Bobbin

In this article, let’s take a look at the lineup of the TMC Ceramic Bobbin EVO series and how to choose the right model for your needs.

The lineup

The TMC Ceramic Bobbin EVO series offers seven models, with three key factors to consider when choosing: Tube size, Arm type, Arm length:

• Tube size — Standard, Fine, Heavy-Duty
• Arm type — Straight or Bent
• Arm length — Heavy-Duty Long Arm (available in Straight only)

Tube size can be identified by the color of the tube:

• White — Standard
• Gray — Fine
• Black — Heavy-Duty

Model Characters

Let's break it down simply. Here's a quick summary of each model:

• Standard — the all-arounder
• Fine — best for fine thread
• Heavy-Duty — built for heavy patterns like saltwater and predator flies
• Heavy-Duty Long Arm — made for handling larger-size bobbins

Arm Types

How it could be the differences of the arm type.

• Straight — an all-around type that suits any tying style
• Bent — built to maximize hold

Another key advantage of the Bent type is that it allows the thread to run more directly in line with the tube. Compared with the Straight type, this helps reduce contact between the thread and the tube, resulting in less friction.

Example: Thread runs through the Bent type
