I've never put any stock in the arm stripes needing to match the waist stripes. And in a world where the Kachina jerseys are some of the NHL's most popular, I don't think you can accuse a few silver stripes of making things too busy. Our logo isn't any busier than many of the "classics", and I think that once you're in a 'busy' zone of the jersey you can go all out as long as you keep other areas of the jersey clean. You need some clean areas and some visual interest highlights. That's why I didn't like the phantom yoke we had in the RBK era- that was an element added to an area of the jersey that was plain and clean before. We also don't have contrasting pants like many teams with simpler jerseys do, which keeps the overall look simpler despite the louder stripe.
Personally, I find the more modern reds a little too bland. They need the full color flag stripe, the faded thing is just an embarrassing half measure. It's better than the generic practice jersey reds, but our original uniforms had lots of visual interest but were never overwhelming because they just put more interesting things in a limited set of areas while leaving the rest plain. They didn't try to add design elements in new places like down the sides or in armpits, or do wavy things around the shoulders- it was just a simple clean traditional hockey jersey design but with stripes that were a little louder and a modern font.
Visual interest is good.
