For Gills I almost always use Bison...which is black and gold....on a black TM head....and only use 2# test line and sometimes 1# test. I fish a lot of lakes, and catch a lot of Gills.....that color out produces any color I have used. I find Gills prefer darker colors....at least on the lakes I fish. Those include clear, deep water reservoirs, and small shallow lakes and rivers.
