What kind of Siglon have you been using?? I've never had good luck with the stuff......Have tried a few different kinds and don't think I have ever lost so many floats in my life. Can remember on a number of occasions setting the hook on fish only to hear the classic shotgun pop of the line and wave bye bye to my whole rig. I've been using Suffix and Berkley Maxx for a while now with good results..
Siglon F in 10# test. 12# has been good too. I have not needed heavier weights so far on my medium set up.
Good to know about the break offs. I think the Japanese ratings are a little lighter than US ratings, so I recall. Haven't broken off any clean hookups but I do fish a little light, and tend to horse it, so just a matter of time. And some times I go all all spaz and can't figure out whether to set the rod hard or grab the reel, or both, or what hand is where. I have been centerpinning for 3 seasons, and think another 2 might be useful.
I think there are several good starting points on centerpins and line:
1) Floating line is easier to mend with less float movement and less distance between tip and line. 2)Long drifts (really long) are typical of centerpins in the "best" drifts, and line stretch is a bad thing, so braids works best there. I think a floating braid would be best, so I tried Hydrofloat which didn't work for me, wouldn't freespool. 3) A looonng rod holds the line off the water and "tight lines are best" but the length gets in the way in many bank spots. My next rod is 13' 6" minimum, current is 11' 6" Raven.
How are the Suffix and Berkeley Maxx for floating?
