Eddie, the Select is just going to get your grasses.  Instead of me typing all this, look at this link.

http://www.uaex.edu/Other_Areas/publications/PDF/MP44/M1_Soybean.pdf (pg. 8 of 13, look at the reflex, flexstar, and firstrate.)

Here's another link to weed responses. Kinda hard to read so you may have to print it out.

Hope this helps some.
