Good luck with the helmets Leigh. I only played to age 14 or something before choosing tennis instead but never wore a helmet. Feel stupid now. Noone should be without a helmet at any level or age group.
Edit: Actually think the only time I ever did wear one was an end of season friendly game where we reversed the order and I got sent out to open (I couldn't bat at all) so was scared of the fast bowlers! I actually hit a 4 too (yes they were so rare I remember each one!).
