Hey Lazy. What happened to your RDK-200 ? And how's that High 5 coil fitment ? ls it loose at all or a pretty snug fit ? I know you love your GS & it's up there too, but what makes the SV4 king over the Symphony for you. Thanks! Edit: Nevermind. Found it! http://fuckcombustion.com/threads/supreme-vaporizer.317/page-178#post-1307149 Damn man. Your making me want a 4!
