I have a new(ish) Giant Roam 1. The whole bike is Deore but has MT200 brakes which I've read is bottom of the barrel. Most of what I do with it (which is why I bought it) was for rough Country roads, and rails to trails and such so the brakes have been good enough so far. Today I did a ride that had some more challenging descents on some gravely hills and I guess the brakes worked fine but didn't feel like I was confident in their control, they felt plastic and flexy if that makes any sense.

I fully understand that it just might be that I need to learn to control them better but I was looking on line at parts to upgrade. A lot of the newer/higher end models are quite pricy but there's some older Deore M505 and M596 that are a great price point.

I guess my question is are the older Deore designs better than the new MT200 since I know Shimano trickles down technologies, so is it a worthy upgrade?
