RY's do well in Les Pauls. The Crawler will be warmer. I have the Crawler in a swampashbody, which is quite percussive in combination with the ebony fretboard, and it is very balanced, warm mids, round topend. Could be to much for you guitar. The Crawler is way more classic sounding then the RY,
For Les Pauls I think Mules are versatile. They cover everything from clean, classic rock to metal. You cannot go wrong with Mules. If you want bite in the uppermids, RY's are spot on.
