Toying around with how I'm going to run my 414s tonight at Tortoise, and found an old KM235 t-bar in the closet, missing the two thumbscrews on the ends used to secure shockmounts. So I mounted joined with my other, complete, KM235 bar to get a broader spread out of my 414s. Including the extension of the shockmounts, I get nearly 24" spread (breaks down to ~8" per KM235 bar + ~4" extension from each shockmount). Should be plenty for ambient recording in the mainly small venues I frequent. And, it packs up darn small.
Edit to add: Because of the hinges, I'm also able to arrange for splits less than ~24", as well.
Now, if only I'd motivate to built a j-disc one of these days...
