Only ever owned a Diana 34 and Weihrauch HW90, so I thought I have what looks like a pretty cool package. The only thing I'd change is to increase the tank diameter about 3/4" and increase the length by 1.5". Would roughly double the capacity and still a compact package.
Edited: Also just...
I picked up one in .25 from UA on sale w/free shipping. Also bought their carbine stock. Added a DonnyFL thread adapter and their Emperor .25/.30 can. Talon Tunes hammer mod, 1-4X Bushnell illuminated German 4A reticle scope, Keystone Accuracy mount. Looking forward to Spring cleaning.
