The goal of using a sink tip is to get the fly to depth. By adding more leader, the fly will most likely ride higher than the tip of the line.
The norm is to have a foot long butt section followed with three to four feet of tippet material.
Not if you're useing a very short one off a sink tip. Fly just 'wiggles' around in the water behind.
