Any chance you would be able to comment on the internal head shap of the Hebo Zone 4?

I went for a HEBO classic trials helmet after my standard open face was just to hot.

I finally got a Hebo Zone 4.  The down side is they sent me the wrong color so I have to see about getting that resolved, but I was able to check size and fit. 

Head shape from what I can tell is more round than I had hoped, it doesn't seem to bad so its a level of between round and oval however with my very oval head it isn't the best helmet for my head.  I suspect based on what others I have talked with the Airoh TTR would fit my head better, but I think for the price and fit the Hebo will work ok.  In short I can live with it as it will not cause pain or discomfort though it isn't a 10 out of 10, I am hoping the venting and everything else it will end up being at least a 7 or 8 out of 10.  It will take a ride or two to know, and have to get them to send me the correct helmet color first so maybe a few more weeks before I can give a full review.
