Worth using search partners in Adwords for my situation?

I have a few hundred campaigns all targeting [exact match] keywords only on Google search and have exhausted my traffic there. If I try to expand the campaigns into search partners, am I likely to see a massive downturn in traffic quality (as in, less targeted traffic) and should create new campaigns to test this? Or can I simply check the search partners box in my existing campaigns' (same bids, same tracking) settings and be confident that I will only get [exact match] traffic from the partners? Will I be dealing with a lot of bots and traffic from unrelated sites that game the system if I use partners? Thanks for any help,
