Thanks. I'm still figuring out what I want to do during that quick sweep spot. Haha, it definitely won't be the sloppy thing I layed down in the clip. As far as your Mark IV, it's a tough call. I used to have a Mark IV and loved it...but the Roadster just fits my style a little better. I would definitely like to pick up another Mark IV at some point though. I guess it just all depends on what you're after. Honestly, out of the box the Mark IV blows the Roadster out of the water...you can just plug a cable into one of those and get a killer tone totally dry without anything else. With the Roadster, you almost have to use a boost to get a tight sound out of it. They're voiced really dark so you have to do some playing around to get it tight. For me though, running the Roadster with EL34's and a Maxon OD808 I'm able to get most of the tones I'd ever really want.
