It's an interesting one really, I've always gone with the same guidelines and used the traditional name, but I can certainly see an argument for changing it, with the stadium only a few years old and the name has been there since inception, the name is now synonymous with the stadium.
Deva Stadium is the Leap 76 stadium for this season, but I wouldn't have suggested we change that as it is only a season long deal.
In this instance I'd lean towards changing it.
