I'm in the same boat. I'm fluent in my knowledge of theory and what notes to hit, I just can't whip out those patterns at blazing speeds. It's like when I watch my training videos of howe, gilbert, and others, they'll play a pattern slowly, but once they speed it up, it sounds completely different. Guitar One done a issue focusing on strength training. Mostly it was really focusing on the pick hand doing alternate picking with string skipping using chromatics, pentatonic, and other scales. That's what I've been doing. Indeed it's super fuckin boring at times, but will definitely build strength for speed.
