Any recommendations on period panties???

I've been researching a lot today after purchasing my first Lena cup. And in the last two months I've switched from tampons to Flex/soft cups. Seems like a lot of these panties are meant to be worn as back-up to what you're already using. But I want a pair that can just be worn by themselves without having to shove something up my who-ha or without having to have a big bulky pad in. I hate the feeling of pads no matter what the size. I've heard Thinx is really expensive. I've also looked at a few other brands - like Anigan. Curious to see what others use or like for just using the panties. Thanks!
