## Questions & Answers

**Q: I need stiff leader material for hoochies behind a flasher - is this material stiff and well suited for a hoochie leader?**
A: Plenty stiff and knots a lot better than the blue and is literally 1/4 the price

**Q: Whats a good test pound leader for #20 and #30 brain main line?**
A: I have had problems with light line.  I would stay with at least #20, STS is brittle.  I stick with maxima, it’s more visible at #10, but loses much less fish.  It’s the choice between a few more hookups, but you will lose more fish on STS since it is brittle, especially with braid mainline.  Take a piece of the STS and try to break it with an overhand knot to test it before you use it.  At #10 my 5 year old could break it with his hands, so I never used it again..

**Q: What is the line diameter for 6lb?**
A: .008 inches

**Q: What diameter is the 12 pound test?**
A: .31 mm is the diameter of 12 pound test STS Trout and Seelhead.
