Arrange circuit breakers in panel


Hello
           I've been following the discussions on this forum for many years, first time I've posed a question. I am in the process of adding two more dedicated lines to my rig. I was wondering, has there been a consensus on the best location, within the main service panel, of the placement of the audio/video breakers? I realize load balancing will dictate space used, but I've read that folks will place double pole breakers at the top of panel (in my case Square D QO 200 amp main panel) and some prefer single pole breakers toward the top. Has anyone experimented, come up with a better arrangement of the breakers? As long as I have the panel open, thought I might try to squeak a little more SQ out of the rig. Thanks.

   Thanks for reply. I've already run Diamond 10/3 w/o ground I found in a small hardware store. I believe the spiral configuration is all the noise rejection I'll need, since I live in the sticks. Was more interested in the mapping out of the A/V breakers, whether their position in the panel, either top, close to entrance feed lines, or down towards bottom away from household double pole breakers might help in noise rejection. 
Thanks 
I just bought a Square D 100amp. It has six spaces to mount one main breaker and five double- or ten single-pole ones.
I would recommend making sure your "audio/video" breakers are definitely on the same pole.  In most standard US panels, the poles alternate on each sequential breaker position.  So you would have to "skip" a breaker location in between each audio/video breaker so that it's placed on the same leg/pole. 

A normal US 220V breaker takes two breaker slots/connections and uses both 110V poles in a push/pull configuration to produce the 220V.
