RTi70 upgrade

[team_canada]

I currently have a pair of RTi70's as my fronts. I want to purchase as set of RTi8's and move the 70's to my surrounds. I am upgrading to a Pioneer Elite VSX-56TXi 7.1 receiver and will be using my current surrounds, R15's, as my rear right and left surrounds. I am not sure if I should leave the 70's up front and use the 8's as the surround, or sell my 70's and go with a set of RTi4's as surrounds. Eventually I will be replacing the 15's with 4's as well. Any suggestions or comments would be appreciated!!

I use towers as my surrounds also, I feel it's best for my setup need's. Towers as back surrounds have a nice effect as they can handle the bass in a movie sound track.

What is your set-up. Are the towers too low for surrounds?? Or does is sound better having them at listening level. Currently my surrounds are mounted to the back wall about 8 feet up??

My family room where my HT / Stereo is located is a large open area with a half wall. So this room is my kitchen / kitchen bar / dinette / family room. My dinette backs to my coach facing my TV so this back half wall is where I have my RT800i's / using the RTi150's as fronts. As far as ear level that is a little hard to setup toeing in or out a little, proper sound level setup is crucial.
