In using Rising Stonhenge off the shelf with no acid soak I was able to get
a Dmax of 1.45 with this mixture single coating using about 2.5 ml of
solution per 8X10 sheet of paper. That is higher than I have been able to
get in the past single coating Stonhenge using either the regular VDB
formula, kallitype or palladium. These readings are for native kallitye,
with no toning.

1.45 is really good DMAX for VDB

Have you acidified Stonehenge in the past for printing VDB? I have been able
to get a DMAX of 1.5 with pure palladium + NA2 (1s mix).

So you aren't using the 26k any longer?
