Looking back over recent seasons there is something resembling a pattern, IMO. Every 3rd year the kit is mostly red (2004, 2007, 2010), with a very traditional mostly white shirt (2006, 2008, 2012?) and a mostly white one slightly out of left-field (2005 v-band, 2009 high-band, 2011 sash-band), completing the cycle.
I looked (as always
) at Hull FC for comparison and it has to be admitted they have knocked out some very nice shirts in that period, especially if your tastes lean toward the conservative. Even that 'virtue' can be taken too far though - 2006 to 2009, they essentially had the same shirt 3 years out of 4. 2006 and 2007 were very similar and 2009 they basically just reversed the black and white. In fairness they don't have a stock variant like we do with mostly-red, 2008 was an excellent tradional effort and in 2010 they showed that change doesn't have to look gimmicky.
