oh really?? they work good? are the RSCs good or just go ultimate?
I don't have experience with ultimates so I can't comment. I did however have some chatter with the ice tech rotors but I blame it on 2 year old rotors with the new set of brakes that have a different surface area than the shimano's. I have a set of centerlines waiting to be installed if the chatter bothered me enough but it just went away.
As for recommending one brake over another, I do like the modulation of the guides over the 785s. Shimano's are definitely easier to set up where I have to mess around with the caliper a bit to get things lined up without rubbing. This also may be because my rotors are slightly not aligned since they're kinda old now and that shimano is servowave to keep the pads far away from the rotors when the brake lever isn't engaged.
I also do all my maintenance so I have the luxury and patience to bleed my brakes. SRAM brakes do take longer to bleed but I have more control over the bleed than the shimano's.
There was one time I got my 785s running relatively fine when I completely drained the system and refilled the system. I've even put my orbital sander on the brake line (no sand paper but just to get it to vibrate) while bleeding to get all the bubbles out. I've even paid a shop to bleed my brakes thinking it was my bleeds that were bad, but they still pumped up. That's when I had enough with those brakes. Also, I went through 3 xt derailleurs because they kept getting bent (not my hanger either, I have an alignment tool to check). Now I'm on sram drivetrain.
Long story short, I was convinced through forums that shimano's were the best, but in my experience, they didn't fit the bill.
