Performance of the Micro Diameter Fly Line

As the name suggests the Micro Diameter Fly Line is very tiny. Yet, I actually expected the line to be even smaller in diameter than it is. In comparison to a Guideline Fario fly line, the head is only insignificantly smaller. However, the fly line was especially designed for the Arctic Silver Innovation fly rod with the free flex system. I have to admit that the combo fits quite nicely.

Moreover, I appreciated the dull grey colour, which is not as clashing as other fly lines do. If you plan to go to New Zealand, a dull colour of the fly line is a must (according to some guides over there).

Summary of the review about the ASI Micro Diameter fly line

The MD fly line by ASI is well designed fits perfectly to the rod of the same brand. Not only the design of the line is well done, but also of the box in which it is delivered. This packaging functions as well as a fly box. However, as you can see while comparing the specifications of the brand and my pro and cons, not all of their promises are fulfilled. Assumably, some information by ASI are rather marketing tools rather than features relying on the actual behaviour of the line. Still, it is a decent fly line which I love to cast with my ASI fly rod.
