Does anyone have a recommendation to set a Goal BFI?

When I started the diet 2 months ago I got a BFI test from my gym and was at 325 lbs ~ 28%.

So I was carring 91lbs of fat, which would mean that I would be at Zero fat at 234lbs. Correct?

Ok, so obviously I don't want to set my goal for Zero Body fat. But what is a good Target to set? I know it will come down to how I look and feel. I was thinking 250 to start, But fitday's graph shows that as Severly Overweight (I am 6'5").

I know that it varies between muscle tone and bone structure and all that, but I am curious how you came up with your goal weight, and maybe can give me some insite other then me just shooting in the dark.
