Coral Nick or ISA Browns

[kt.]

I have had bantams, Black Rocks, White Leghorns and now have ISA Browns that are currently in moult.  When they are to be replaced I am considering Coral Nicks as they supposedly lay and extra 35-40 eggs per year but I do not know anybody who was had this variety.  How long do Coral Nicks lay for and are the eggs a decent size?
