I will shortly be off to a Cricket Carnival @ Orange, added to this Im not quite certain due to distance from the action
as to what lenses will be effective .

I have the D300 with maybe the effective 70-200 VR f/2.8 or 300mm f/4 with a 1.4 TC attached.I am
trying to pack as I don't want/need everything ,trying to get some sightseeing as well.To which I'll being a 18-105 Kit lenses with this.

I believe that the playing oval would be over 50m distance would it be better to have a fixed 300mm or the 70-200 .Im not too sure whether the Kenko DGX 1.4tc would suit the 70-200
as well as it works on the 300mm f/4
Thoughts experience anyone
I do hope 24gb of CF cards are enough

cheers
