pentahydrate or anhydrous?

hello

During my internet research into making better Van Dyke prints, I
came across some very good posts by Sandy KIng on the VanDyke
process in the archives. Realizing that the rapid fixer I was using
is no longer going to cut it, I've decided to purchase some Sodium
Thiosulphate. However, Sandy fails to mention (along with many other
good articles I've found) whether to use pentahydrate or anhydrous
Hypo. It seems that anhydrous is the right choice but I just want to
make sure.

thanks
