Hs33's are very reliable, but because they are a rim brake, if you get a buckle in your wheel, they will feel weird. I have a DD CZAR 20" that came with Juicy 3's, Which were the stupidest brakes ever! I went through 2 back brakes because the seals broke and fluid leaked onto the disk, so I dont recomend you get a Juicy 3. I then got two Hayes Stroker Rydes that were real good for a long time, but with constant hard pressure on them, the back began to leak. So now I have the Hayes on the front and a BB5 on the back, with Avid lever which is going great! Cables dont have as gooder feel as hydrolics, but work better. I recomend a BB5 or BB7 because they have real small pads, meaning better braking power. And thats my two cents, Back to you Tomm.
