Definitely read the link Jeff posted. I don't wanna sound like I'm bashing Rahr or anything. I'm sure a lot of people (and many pros) use Rahr to make good beer.
That said, I used to buy a lot of Rahr pils malt because it's the least expensive base malt at my LHBS. I've since switched to Weyermann pils and Simpsons Golden Promise for my base malts. The friability is outstanding, they crush well without shredding husks, and I've noticed increased efficiency in my mash and improved flavor in my beer.
There are a lot of different maltsters out there, and some may be better than others, depending on the kind of beer you want to make.
