Thanks for your comments. I do appreciate them.
I just sold a bunch gear so the 23mm is what I had left. But now I'm thinking about a used 18-135mm f/3.5-5.6 R LM OIS WR. According to kolarivision.com/lens-hotspot-list the 18-135mm shows IR color vignetting. As I shoot mostly B&W, I'm wondering what that might look like after lens corrections in editing. Maybe a creative plus? If nothing else, 18-135mm gives more flexibility in composition. Probably keep the 23mm for the speed.
You might be surprised. Many normal photographic filters can give interesting results on FS conversions. Variable Neutral Density filters usually pass IR more than the visual, red filters are typically 590nm, but will all give fairly similar effects. Orange & yellow filters are mostly long pass types (hyper colour), some blue filters such as the kodak wratten #47 give super blue like results...
Yes unfiltered FS can also be great, often giving fairly normal colours with just a few items having altered looks (at least in the UK, changes may be more drastic in California, your cool temps would be a summers day for us!).
For many years I would shoot unfiltered FS with my Sigma DSLRs (their UV/IR blocker is in the lens mount, removable with a thumb-nail and almost as easily refitted). There being no CFA and with each raw channel being almost polychromatic, the result was usually a heavily-weighted magenta image. The only decent FS came from RawDigger's RGB conversion (LibRaw). Sigma's proprietary converter was a waste of time for FS. Not only that, no live view did not help at all.
Imagine my pleasure after getting my Lumix DMC-G1 done by LifePixel. I was surprised that they did not remove the CFA but that was more than made up for by the live view and results with the WB set to 3000K. With usually-brown sky results it was easy to turn that brown to blue (or any other color for that matter). in the GIMP

Excellent image @Athena. The hikers add an extra dimension. Well seen and captured.

Superb image. This has a less extreme IR look. Like the results.

I like the way that solitary cloud breaks up the large dark area of the sky!
