I use a couple feet of 6 lb flouro attached by a tiny spro swivel so smelt don’t loop it up and then a # 8 gamy octopus hookI use NO weight, I found that if it’s in the vicinity of the bottom of the ice the rod going off can catch a split shot on the underside of the hole and you don’t get a full swing.
I love the straight octos they’re not circle octo just straight octo
