Love em.  I have tried all other types of bdu style pants, and these are hands down the best.  But if you already have a pair, then you knew that.  Love the mag pouches in the side pockets, as they hold my notepad, cell phone, rubber gloves, and extra pocket knife in a very organized manner.
My only suggestion to 5.11 is to put a dedicated knife pouch on the front of one of the legs...
