I agree with Matt, I cannot see any streaks either. This could be a scanning problem.
I thought I see could see them in the post #121 images, but not equidistant from the sides: about ⅓ of the way across from left and right, running vertically relative to the image. If I'm looking at the right thing, that symmetry suggests the sides of some liquid effect running down the film centre. In post #114 the more obvious and bulgy streak also has a 'liquid' signature.
Either its a scan artifact or the streaks are actually in the sky and you are getting pictures of them.
logan2z, have you seen the post on FADU that suggests that the kind of mixing which is OK for all other developers may not be enough for "old" HC110. The post suggests a method which may or may not work, assuming of course that HC110 itself is the problem
I just cannot rid myself of 4 thoughts:
1. Out of the many tens of thousands of times( a conservative estimate?) of mixing surely in a few of those times the mixing was not thorough enough for the issue to have arisen? So has this problem in fact arisen but we on Photrio have just been not in the few to have ever experienced it?
2. We are now so flummoxed by this problem and vania's that we have got to the point of effectively "clutching at straws"
3. If the issue centres on the difficulties of mixing with the old syrup HC110, does the new much less syrupy HC110 solve the problem?
4. Is the problem for whatever reason(s) solved by the use of another developer for those who have been the unlucky few to be adversely affected by the problem?

In the meantime, I developed a test roll using Ilford DD-X late yesterday and the negatives are still drying. I'm going to scan them this evening and see how things turned out.
I've shot rolls at various times of the day, I've used multiple cameras and lenses across three different 35mm systems, some with hoods some without.The other possibility is that there is a problem with the actual capture of the image. Are you shooting at mid-day? Are you using a lens hood? Have you sent off a roll to a commercial lab to see if the streaking persists? The fact that the streaks run from sky to ground regardless of orientation suggests this is not a development issue.
Well, I scanned my roll of film developed using Ilford DD-X and...
No streaks!!
I don't know if that proves the mixing theory or not but it certainly looks like this is somehow related to my use of HC-110.
I'm going to develop another roll over the weekend using DD-X to see if this was just a fluke, but it's looking promising so far.
Thanks for the report on DDX If you repeat the success with DDX then in terms of there being an issue of some kind with HC110 we would appear to be getting closer to QED - the famous final line required by the teacher after the proof on a geometrical problem

Sorry, but the only proof achieved here will be that logan2z gets better results with DDX than HC110.
There is some not yet identified combination of factors in play here.
Otherwise (nearly) everyone using old HC110 would be complaining.
Remind us what water you are using to dilute the HC-110.
Matt, being cognisant of the sensitivities when a Kodak item is involved I did try to cover this by saying "in terms of there being an issue of some kind with HC110". The "some kind of" phrase was meant to cover "including the processing involved"
Ahh, I'm glad you posted this, you jogged my memory. Way back when (a couple of months agologan2z, try a leader test with your HC110 to see if it fully develops it i.e. turns the leader black enough that when held up to an incandescent 100W bulb the tungsten wires only glow an orange colour such that the wire can be picked out easily.
I am convinced that by dint of time, effort, cost and scientific problem analysis the cause will eventually be discovered. but how long this would be and at what cost in terms of $ and frustration is anybody's guess
This is a really weird suggestion, but what the heck.
I see people espousing the quality of so-called alkaline water for drinking.
In the unlikely event that your water - both tap and purportedly distilled - is weirdly acidic, how about trying alkaline water as the HC-110 dilutant?
