From what I've seen here, Ilford HP5 PLUS, is still being produced but the price is very high for a 50' (foot) roll, US$240 plus from U.S. sellers which will give three full rolls for the A70 cassettes, plus five feet, more or less.
I suggest you make a reusable leader and a tail out of used 70mm to save frames in each roll.
I need to see if I can get someone to send me some trashed 70mm for such a purpose, again.
Also, India and those with foresight and fortunately to have bought and stored many rolls and, in my case, a roll of Tri-x that came in an A70 back, yet to be tested for prior use and in a large partial roll in a 70mm loader.
I still have to order one of the Plus-x areo rolls from India, 2006 dated but you never know when a second or even third loader could pop up; I'd like to have a couple 70mm loaders on hand just to avoid changing rolls.
Cheers
