I'd say go with the Kimber Kable. Even the 4PR or 8PR will be better than the Monster Cable. I used Monster Cable for my surrounds for several years, and the cable fell apart over time. I've had an equally long run of Kimber Kable 8PR going to my sub and it still looks brand new. I replaced the Monster with Kimber 4PR.
Also, the Kimber is braided to reduce noise pickup, if that is a potential problem for you.
