Geez, I can't believe the variety of responses I got on what I thought was a pretty straightforward question. It gives me a lot to think about. I'm still torn between my original two options. I tried a few of the other suggestions to varied success. DDUU to me seems to make sense, but I can't do it with any sorta rhythm or feel. I think having to jump over the 3rd string between the D and the U is causing me trouble. PRetty basic stuff, but it's hanging me up, anyway.
I'm an acoustic quasi-flatpicker at heart, so the straight alt. pattern is most intuitive to me, but certainly not the most efficient. Anyway, I'll keep trying a few different ways, and I guess I'll have to settle into something soon, and just stick with it. I did like the idea, alien, about fretting it note for note, rather than slopping the power chord down and picking the 4 notes. I'll give that a whirl tonight.
Thanks, everyone, for once again proving that, with music, there is no one right way to do anything.
