Geoff,
You know I use the 22 Panoptic, and its very good and of the highest QT.
But I would prefer the 24 as its smaller and as you have 14mm and 10mm Pentaxes, which use the 1.25 barrel. No changeing.
I only have the 22 as I got it at a good price.
If you would like to wait, Mark has the 24 Pano, and next time we observe try the 22 and 24 then decide.
