Some may disagree, but i'm not a fan of Crawlers in a Les Paul, i think it would be too much. Have you thought about putting an emerald in there?
I used to have an Emerald instead of the RY, not enough output & a bit too tight.
Hmm
Well that doesnt really leave you with too many options then!
For my two cents i tried the crawlers in my les paul, then relagated them to the wolfgang as i found that although they were mega thick, they were a tad overcooked for my tastes, and really lacked any kind of cut or presence.
I'm surprised the emeralds weren't hot enough as ive had both emeralds and rebell yell's in the same guitar and the difference in terms of perceived output for me was'nt that great - i guess it depends how much gain you play with (sorry i dont have speakers at the moment so cant check out your clip!)
