the so called white specks are from unfiltered water.
Everything should be crystal clear with filtered tap water or even better - distilled water.
Not having a spectral sensitivity curve here to compare, I cannot say. Sorry.

Heres the spectral sensitivity curve of Technical Pan.
Cropped from Kodak tech data pdf taken from here http://kodak.com/global/en/professio.../p255/p255.pdf
Thanks again. That looks to be close to normal panchromatic sensitization. The pan curve I show is closer to a daylight sensitization whereas the Tech Pan is rather poor IMHO. But, people loved it so who is to complain? Right?
I confess - I love Technical Pan!
Here are 2 shots from the autumn of 2010, shot on a 35mm Technical Pan roll expired in 1985 (black colored canister, yellow lettering)
I used russian Zorki 1 rangefinder, 20mm wide angle lens, orange filter.
The roll was shot as 50 ASA, developed in Rodinal 1:100 for 15 min

This one is from the same day, same place but on Adox CMS 20, shot as 10 or 12 ASA, again Rodinal 1:100, 15 min.
camera was Fed nkvd with its matching original uncoated lens 50mm f/3,5 closed just a single stop from wide open, light yellow filter
What is a shame is that I won't get a chance to see whether I like or hate Technical Pan...
I've added some Adox films to my list, along with that specialized developer for the CMS 20. In the meantime, I decided to try the Plus-X emulsion first, and then move on to the Efke after that.
Trying Plus-X emulsion first, and then move on to the Efke after that sounds like a wise decision, imho..
The slow speed Efke, 50 asa and 25 asa are silver rich, boutique grade films. I can't comment on Kodak Plus-X in its current state, I hope it didn't turned out into one of those t-grain silver economy wonders.
Of course, one should respect the work of Kodak B&W film teams and I am sure the workers there put their hearts into making those products.
Kodak stopped manufacturing most of the films I liked... HIE, Technical Pan.
btw: Efke/Rollei/Maco have alternatives to:
HIE ~ Rollei Infrared 400, Efke IR 820, Efke IR 820 AURA
Technical Pan ~ Rollei ATP 1.1
Also, from slow speed pov and interesting look Rollei RETRO 80S is quite a ride.
I might scan some shots from those this coming week
Someone mentioned seeing Plus-X on the Freestyle clearance page, but I couldn't find that. Was that a mistake, or is this just Freestyle's re-badged Arista Premium?

Anyone got anything besides rumors. The last thing we need is a bunch more rumors. Unfortunately you can't trust anything Kodak says about availability.
Looks like Plus-X its still where it should
A friend in the states mentioned that freestylephoto clear old batches sometimes, so I hope that was the case.
Its says Limited offer @ http://www.freestylephoto.biz/clearance.php
