I'm jonesing for a 6/12 double neck. I'm leery of the cheap Korean models, but I don't want to spring for a $5000 Ernie Ball. I've priced all the components from Warmoth ($1500ish without pickups), so building one may be a possibility.

Anybody have experience with a double neck of any stripe? Any advice on what to watch out for (besides back pain)? Pickup combination suggestions? Control configuration and location ergonomics? Inquiring minds want to know...
