I'm using #8 Siglon F and it's not bad. I bulk up on leftovers for backing and connect the lines with a clean blood knot, and use maybe 60-70 yds of the siglon as the running line.. Like you said, it creates less drag on those long drifts because the line stays on top of the water... But even with a micro swivel above the float, I still get tons of line twist, but that's probably from side casting... I'm also finding myself having to constantly make sure the line is securely on the spool before I start spinning... If you're not careful, the line ends up looping around the handles and not the spool!! This is a huge pain and when that line on the handles falls off all at once, then the curses really ensue!!
What line should I graduate to when I'm not a newbie, oh lord master ruler of the pin Bill??
cheers
