Gut feel is that the Sunday competition for 2015 is experiencing slight growth in numbers in the U15 and below age groups, and slight decline in the U16 and above.
The full analysis on The Saturday U18 Colts comp and Opens Sunday and new U16/U17 comp have yet to be done. The "pathway" at these age groups is becoming like trying to get home via the M4 at rush hour.
Edited to include Friday Night comp team numbers below.
