I remember getting WW at one time. They may not be available now at a reasonable price. The foil one will likely open  if a tube redplates as long as they are only 1/4 watt. The ones I have been using are Vishay Dale. I probably have a part number on the bag - try to remember to look.

Being able to use them as a shunt for calculating idle current is the 2nd best reason to add them.

>>>Bag is gone but the resistors say Dale 1%t1 1535. I know I got these in the last year from Mouser.
