I use HT ice riggers, same concept as the finicky fooler but uses a gator clip to hold the line for the tigger. To me, having a little bit of coiling doesn’t matter with set lines as your not feeling for the bite, it gives a bit of runtime before the flag goes up. Or use a slightly bigger weight. M
Lighter fluoro won’t be as slinky. Using a heavy fluoro leader for pike is great, don’t use any more than 10lb of soft fluoro as the main line (I use seagar red label up to 6lb and invizix for 10lb). Otherwise, fireline crystal fused in 10lb and lighter are very fine and don’t ice up that much. Their “micro ice” is the same line as the open water crystal, so don’t bother with the little pony spools sold for ice.
