Seeing vs Aperture

This might be a stupid question, but what effect does aperture have on seeing (if any)?

The reason I ask is because I find that seeing here is rarely good enough that my 6 mm EP in my 10" dob (200x) doesn't look wobbly - though when it doesn't it's great!

If I had a 12" at 200x (I realise that is a different FL EP), would the image be equally wobbly (assuming we're looking through both scopes together!), or can you push a 12" to greater a mag than a 10" given the same seeing conditions? I realise there would be a difference in brightness of image....
