Is anybody knows difference between regular Defier line and Armillo Defier? Only color or some special properties? 

Armilo has much less stretch.

 

Armilo is a more abrasion resistant mono. It has less stretch also. A very good all around mono, but at the price of most fluorocarbon lines. 

Thank you, guys!

I've got it.

Sunline Deifer Shooter is a copolymer line Armillo is a Nylon line and less expensive, plus availble in 25 lb test is the reason I use it.
