Sounds like you're using nice glass there Bon
The original TMB Paragons occasionally show up used in the ice trade classifieds or over on astro mart. Failing that, there are clones from TS (
here ) and SW that are reported to be very good.
Alternatively the ES82 30mm works well (I use one) for an immersive experience, likewise a Nagler 31T5..I've never had the pleasure of the latter though and both are the best part of a kilogram. Likewise, I've never had the pleasure of the longer focal length Panoptics
There's also Pentax XW and XL 40mm and they work well with the Edge series too.
