[QuadList] Fuji vs 3M tape

[David Dean]

In my experience Fuji 2" seems to hold up better than 3M , usually 3M will 
need baking, I must admit that I do not see many uncut rolls as most of my 
transfers are G spools. Ampex seems ok as well.
The way the material is stored is a serious consideration. If  I  am not 
sure I look at the state of the screws on the spool flanges, if they are as 
"new" then everything is usually fine. If they are corroded this is a sign 
of trouble.
I did do a large archive of 1" B format and Ampex was fine, but Scotch 
needed to be baked 9 times out of 10.
My half penny worth
