1 or 2 Rear surround speakers for 6.1 system?

I'll soon upgrade my HT system to 6.1 from 5.1. I'll have the usual L+C+R speakers in the front and 2 side surrounds and plan to add another one for the rear surround. Now, is it really necessary to have 2 speakers in the back or can I get most of the benefits with one channel/speaker?

I would use one for 6.1 and two for 7.1

Muratc, 7.1 is a futuristic concept. It will allow for seven discrete channels of playback. Pre amps are being sold now with this capability but like everything else in this hobby waiting on the technology could take awhile. For now 7.1 will indeed rob info from the rears to feed the side speakers. In DD6.1 EX or DTS EX the sixth channel is in fact a discrete rear center channel. I doubt this will catch on but only time will tell. Personally I'm still perfectly happy with 5.1 surround sound.
