Not saying one shouldn't be cautious, I have a lot of respect for wakes myself, but the 170 is not really a hazard to safe flight with those big, efficient winglets.
I haven't experienced it personally but I know of a couple instances where an ERJ has been caught in the wake of a 170, parallel runway, and had to go missed. They were very amazed at how disruptive it was. One of them frequents these boards.
