i had some sd 5's on my last bike and now i've got bb5s. i liked the sd5s b/c they were better than the cantilevers i had on my bike as a kid, but i'm guessing you aren't looking for discs. Just get something like an sd5 and upgrade the pads. One of my friends i ride with has lx brakes and they are loud no matter what and they kind of suck at stopping.
