Arm Placement on Bot?

[Po-ser]

I'm sure this topic has been discussed somewhere before, but I can't find it (big thanks if someone can redirect me!). My team has been discussing the placement of the arm on our robot for this year's game. Because of a certain impossible-to-describe design (my best attempt: "the arm swings over in front of the chassis sideways sort of" ), we think our chassis would be more stable COG-wise if we placed the arm all the way over to the right corner. I looked back and found this photo of wildstang from 2005:

And was told that they had a hard time driving, since they had to aim for tetras with the corner of their robot. Could someone who's driven that bot or a similar one tell me if it's true? Also, are there any other notable pros/cons for putting an arm off to the side as opposed to in the center?

Edit** Actually, the more I look at it, the more I think I've got my facts wrong. That arm definitely looks like it's in the center. Question rephrased: Are there bots that have had their arms placed off the side in the past. If so, how do they drive?

Sorry again if this has already been discussed somewhere!
