Well I had a g29 for a while and the 11 inch diameter is so bad but it isn't very immersive. If you are looking at moza they have the es wheel which is around the same size as the g29 but they have are 12 inch mod for it which will probably be good since I have a cs wheel which is 13 inches and I'm really happy with it. But it really comes down to preference. Real cars also have diferent sizes of wheels. My opinion is that 10 - 11 inces is too small.
