Anyone with experience using the Singh-Ray Hi Lux Filter?

I had a thread about this a few years ago, too.
Actually, I have been happily using this Hi Lux filter instead of a UV or clear filter on one of my lenses. No problems/no issues.
But, I'm wondering if anyone has noticed any differences with their images using this filter....especially due to the "warming" feature (which supposedly improves "chromatic clarity.")
Yes...I realize the warming can be adjusted one way or the other in post processing.... I'm more interested in the actual effect that may be taking place while taking the photo.
I'm considering getting another one for a new lens I just got...
Thanks.

No comments?
In that case, let me rephrase things....
If you are using the Singh-Ray warming polarizer as opposed to the neutral polarizer (I do!), I'm wondering if you think there's much of a noticeable benefit in your "negatives." That is, do you perceive any improvement in your preprocessed image quality (IQ)? And, with respect to the warming effect, do you shoot with Auto White Balance or Daylight settings?
Thanks.

Well....I decided to get another one of these for my new lens (85L) since I've had one on my 24L along with warming polarizers on couple others. And I've liked the results. I've been happy with Singh-Ray, overall.
But I had changed to Auto WB for some reason a while ago....and I'm thinking of going back to Daylight settings in my cameras. That would obviously provide more "impact" from the warming effect. In addition to the other benefits.
