Hi sparda15 .. can you post a pic for us ? I assume from your question ``will getting swiss and bleaching knots make a difference`` that your front hairline is French lace? Swiss is normally better for invisibility at the front so you could have a French base but specify Swiss front.... any combination of base materials is possible/available. Knots are bleached at the factory, particularly at the front... post a pic of your front there if you can... what exactly is visible ..is it a shine or a dark-ish `line`? Paul.
