120 film for Hasselblad 24 backs

[hap]

Is there really great advantage with the 24 backs? where do you get the film these days.
thanks

220 film is long discontinued, so unless you want to find outdated film you can't buy it any more. When pros shot weddings with their Hasselblads back in the day having twice as many shots on a roll was a considerable advantage.
