hey, i went through your nightmare last year and i tell you what i learned from all that experience. mainly the shot line, as i have been fishing with hi vis line for over 10 years till i started heading out more and there was more retying happening. everything i am about to type i learned and each had pros and cons for me.
hi vis line.
PROS;
-you see your line,
-cool colours,
-others can see your line
CONS:
-you either need very long leader 4'+, now if you are rich or like to waste money that is fine, every time your hook breaks off, you have to put 4' of line on again. you run out of leader and waste money imo.
- or you need shot line.
Shot line.
PROS:
-you don’t damage your leader as you put split shots on the shot line.
-double swivel make it almost tangle proof.
CONS:
-you create two extra knots that you didn't need, and makes your setup all the weaker.
-chance of you losing fish raises immensely if any of your knots have flaw, plus the fact any knot creates weakness.
- your shot line plus your main line might create too long of legnth and if you change holes on the water, you may have to cut from your shot line to hit shallow depth which will waste your split shots and just become pain in the rear.
normal line of your choice/ low vis
PROS:
-cheaper than most high vis lines
-you can choose any line you want with full confidence without worrying about losing fish, or line snapping.
- you can set the depth of your float at any height and not worry about a thing.
- you save tons of both money and material on using only 18"-24" leader of your choice.
CONS:
- chance of entangling with fellow fishermen (that can happen with any line if people are not paying attention).
-you might lose the sight of your own line BUT(once you become or if you are a good centerpin fisherman) your line has to be very tight with your rod tip high so there should not be any slack, and as soon as your float goes down then you can set hook with confidence. this also depends on your reel and how good it's starup intertia is. not how long it spins, but how fast your line unwinds as soon as your float makes contact with water.
putting your float on your shot line
PROS:
-I don't see anything
-but it might help with line twists.
CONS:
-the swivel above the float can easily damage and break your first two guides (buddy did it to two different rods, till i told him why he keep breaking his guides)
-first knot breaks, say goodbye to 1-5 dollar float and all your shot line.
-your float will not move properly in water and it will make it hard to guess proper depth( it does not affect catching fish ability, I have seen my buddy catch without any issues)
your backing and line length sounds just fine. now i use light green/clear main line, and FC leader.
about siglon F, it is very close to IGFA standards(meaning it snap close to what it actually says on the box:, therefore if you are going to buy a leader, buy a leader that is thinner in diameter than your siglon F, don't follow poundes, as some leader line like drenan 6lb is probably thicker than siglon F 12lb+. or you are going to have a bad time losing fish after fish as it drags your float cause your main line snapped. use fluorocarbon leader as they are abrasion resistant compare to mono. i personally use davy knot with thinner leaders and trilene knot with thicker leaders. the time of the year and how feisty the fish are also matters, but those two are my go to knots. davy is better for winter, because how simple it is. i personally always stay away from any form of clinch knot for FC. if you use eggs sacs, use size 10-16 single egg hooks and they have short shank and harder for the fish to feel, not sure of your experience with CP, start with larger hook and scale down as you get more skilled, as both setting the hook and keeping the fish on a centerpin is hard at first, specially with steelhead,
I hope all this help.
