Hey Pierre,
Not bumpy since I didn't start learning this until coming to TG. I actually think the travis picking version is much cleaner than Paul's raw strumming technique. It works for him but is very un-technical and he just did what he figured out himself, no one would have ever taught him to do it that way. I also leave out a note from the tab on the pinch-thumb-sinlge notes part - guess I learned it that way from Neil's video and never really used the tab. I didn't even realize it until after I had the song down pretty much. The extra note makes it sound a little more like the strum version maybe but I think I like just the cleaner simpler sound and probably won't change it - especially when adding the vocals, it's plenty busy enough. Thanks for commenting.
Scott
