Anyone over 60 will say it was Wakefield which was a slightly bigger derby than Bradford.
Anyone younger especially those who joined us post SL will say Bradford.
Castleford have been a thorn in Leeds side from time to time but it's never been consistent enough to matter. Nothing will change as next season Cas will go back to mediocrity just as Wakefield did after 2004, 2008, 2009 and 2012 when we to managed top 6/8 and in our case nearly got to Wembley.
In reality the only rivals Leeds really have are Saints, Wigan and Warrington - the only other three teams who have recently won anything. I'd include Hudds but until they actually do what I just said they are not in the club.
Wakefield have the most potential in theory, near to Leeds, bigger than Cas etc etc - in reality it's just a pipe dream unless BV does get a revamp and a sugar daddy appears.'"
I think it also depends very much on which part of Leeds you come from/grew up in. To me it was always Cas (though undoubtedly Bratfud overtook for most of the SL period).
Leeds-Wigan is always the biggest rivalry cross-pennine IMHO. Even when Leeds and Saints squads went through a spell of seemingly detesting each other I always felt it was a more friendly/less intense rivalry between the fans.
