Having done both, if you are feeling stuck in LR on 7Sage definitely try Loophole. It is a very engaging book with a tone somewhat similar to JY's videos. It really does change the way you think about an attack questions. That said, for Loophole's magic to work you HAVE to do all the drills and practices she says and use her method every time you read an LR stimulus. It's the only way for it to become second nature. Good luck!

I usually use the highlight feature to highlight the important words from the question stem before reading the stimulus, then highlight the conclusion or other relevant phrase while reading the stimulus for the first time.
