I think that is the first time I heart the RY described as dark and mellow. xD
Anyway, sounds like you got a real keeper with that combo!
Are you splitting the crawler too or just the RY?
Oh and a little thing, you say coil tap, but I think you mean split.^^ Coil tapping is really rare and therefore is often used as a term for coil splitting, which is turning a coil of a humbucker off. Actual coil tapping is when you got a special PU where you can use the full winding or just a part of it, leaving out quite a few turns of wire, making it effectivly underwound in most cases. While this is something I think is really cool and would like try with some overwound PUs it is really, really hard to do it is very rarely ever seen.
90% or more of people get what you mean by coil tapping, it is just a little pet peeve of me ;)
