I can't say I've noticed too much change/ texture & I've been buying the new foil wrapped ones? It might be me as I alternate low fat crispbreads.
There is a great difference in the percencentage of fat per 100gms tho'. I'll only buy the original or the rye ones.
OT - Tesco have lowered their choices on crisp breads/ rice cakes - my daughter's a manager ( well outside & varying in Welsh supermarkets) & says she can't order for individual customers - obviously but they do see to be cornering the veggie stuff to one section of chilled/ one of freezer even in the biggest stores here!

OT - again , why as in Gordon Ramsey do chefs ridicule veggies?!
