i wear low rise jeans, and my panty of choice is victoria secret..i wear the little t-strings from the very sexy collection (picture dental floss with a small piece of material to cover the front) or the v-strings (slightly more material on these, front and back) or thongs from the pink collection, along with their boy shorts..i haven't heard any complaints of lines so far. i think the v-string and t-string you have less material to worry about showing, and are my preference to wear. good luck in finding something.
