New Gi, when is the right time to replace your old one?

I’m going into my 4th year with my current 14oz Gi. Its starting to "break-up", at the creases etc. I love this Gi, it’s served me well, but scared of getting a new one and I don't think it will fit me the same or feel the same.

I currently have a 14oz Blitz White Diamond Gi, Japanese Cut and size 190 (6)

I have other students who have bought the same Gi recently but their Gi's don't fit them the same.

What recommendations do you recommend and the Gi gets some usage from grabs and throws (similar to Jujitsu throws etc. Although I don't want to get a Jujitsu Gi unless it is highly recommended)?

Oh also it would have to be at Trade prices too.

Thanks
