I was considering putting my E6 slide 120 films up for trade in exchange for B&W rolls, but a friend of mine was trying to convince me not to, assuring me that later in the years, those precious velvias/provias and Ektachrome's will be impossible to find...
I wanted to concentrate on the B&W process but the argument of later wanting to shoot them and not being able to, considering the current state of the market, made me reconsider.
I suppose the most reliable player at the moment is ILFORD and I don't see them producing color films anytime soon...

Should I hold on to them because of fear or just drop them as I am not using them atm anyway?
