Is it better to constantly seek new problem or redid problems we can't solve a month ago?

Exactly the the title says, I currently keep track of the problems I can't solve. However, even though I had done more than 50 1700 rated problems sometimes I still struggle... so should I redo the problems I can't solve or just solve new problems until I'm comfortable with this rating? Thank you!
