N1R is BR at 1.45° tilt and even though it works, is smoother, and clutter can be removed I don't think you'll like the presentation during storms. The BR 0.5° tilt is most representative of precipitation during a majority of storms.
We are stuck with CR due to the NWS deprecating the product and not the WU this time. I figure the other BR tilts will be killed off but this is just speculation. The "blocky" short range CR appearance is due to its lower spatial resolution on a 1.1 * 1.1 nm grid. It has one-half the resolution of the Base Reflectivity product. I don't like all the clutter especially at night and no clutter=1 doesn't work in CR.
I just got this feedback from a retired MET: I think the CR feed will usually appear similar to the 0.5 BR feed, but will at times make rain appear heavier than it really is. Ground clutter suppression is more difficult in CR. The CR looks at a wider slice of sky and is more likely to detect non-precipitation objects and phenomena that reflect radar energy back to the radar. These could be high terrain, flocks of birds, swarms of insects, and airplanes. Radar output users usually can tell the difference between precipitation and non-precipitation returns. Nevertheless, radar clutter is annoying and might cause real precipitation to be harder to interpret.
