I think that it makes perfect sense to use Craven Park.
For most of these players it is their first game as a professional rugby league player and definitely their first time in a Hull/Rovers shirt (other than the 3 Hull lads who played 1st team). It is also their first taste of a Derby.
I think that they deserve to play at a venue that recognises their achievements so far. Playing it at Wests, Skirlaugh, Hullensions, Rovers back pitch, Bishop Burton wouldn't do the lads justice in my opinion. Brantingham would be fine.
If both clubs advertise the game properly on their websites and Twitter feeds plus they get the info out to all of the junior clubs in the area then I still think we could get a decent crowd and Rovers more than cover their costs.
