What size line is best for a drop shot spinning rig on Lake Fork?

10 lb test in open water. Heavier for brushy structure.

I use 12# Invix with a 1/0 Owner Riggin hook. It's the perfect set up

I keep 20 lb. suffix 832 braid or 17 lb. berkley nano fil on my spinning rods & then use a 10 lb. suffix fluoro or mono leader with a small swivel.

15 power pro braid to 15 fluoro leader. I use the double uni and have had no issues at all.

For heavy cover at Fork I use 30lb PowerPro and 15lb invizx. I use the crazy alberto know to attatch the leader with no issues. I have also used the double uni and few others with no issues, just that the alberto to me is easier to tie.
