My starting point with this is choosing a main line that sinks well, and I mean really sinks! For years I loved the good old Insight’s “GR60”, but now I think the evolution of main lines has progressed so far, that strength, colour and sinking ability are common place. However, my favourite now is Gardner’s “GT-HD”, either in 15lb or 18lb depending on the range I need. The 15lb is 0.35mm and casts miles, but it is super strong and sinks almost like a fluorocarbon. If I add either a 20lb Mirage leader, or a length of Camflex, I am confident that it’s all pinned to the deck as best as it can be. It gives me the option of using a strong main line, that casts easily, but also one with covert properties. I will always use it if fishing in or near snags, in heavy weed or at ranges that I can’t hit with the Mirage main line.
This fluorocarbon is my first choice for most situations where I’m casting less than 80 odd yards. The Mirage in 14lb (0.35mm) will get you out that distance far better than thicker fluorocarbons, but still has excellent strength and abrasion resistance. The make-up of fluorocarbon is more stiff, so it doesn’t go through the rings as well as softer monos, but if you stretch it out before using it, and don’t overfill your spools, it can still be cast decent ranges. I love it, as the clear line is invisible, and soft enough when sunk to lay over all the contours of the lake if it’s sunk correctly and fished nice and slack. I have it hanging down vertically from my rod tips if circumstances allow, and often fish it all the way through to the lead, so impressive is its invisibility in water!
