I'd ram my own Spollettes with a fast powder.  You could make several with a 100g batch under a straight BP acquire and keep.

 

Failing that, fast visco is pretty consistent :

PL6 or PL10 in either shrink wrap or glued into a tube? PL6 would have a mechanical advantage for the very thin ones at 0.25s as there’s a lot less chance of a blow through?
