I know about RE's, infact, Trailmaster released them first waaayy back, but they didn't have braces, just the brackets.....I'm just happy that RC released theirs, cause they are half the price of the RE units and they include the braces as where with RE, you have to buy them seperately.
Some people say they notice a huge difference, some say they don't.
To be perfectly honest with you, I didn't notice much difference in ride quality when I went to my long arms either. They do flex better and give me back my wheel base though.
