When I switched to continental-style I just could not get the motion down for purling. For some reason it was just awkward and took forever and looked icky. All of which made me sad cuz I'm left-handed and continental knit stitches was so much more comfortable.
Anywho, I checked out that video of the Norwegian purling--and that's how I purl now. It was just so much easier for me motion-wise and I like keeping the yarn in back. I know it looks finicky and like extra movements, but for me it's faster and easier. So give it a try if continental purling feeling ooky to you!
Oh yeah...even now though, my gauge is different purling than knitting. But I don't sweat the small stuff yet, I'm still a beginner and at least the gauge is consistently different, if that makes sense.
