Tall Font Russian Muff types

DarnWeight

Noticed that poodle/fuzzdog/pedalparts have recently started offering a Bass-centric Big Muff kit with clean blend and mid control options.  There's a range of options for different versions, and it's the Tall Font Russian and Civil War ones that have caught my eye. 

I've gone through a few different varieties of Big Muff over the last few years, and never held on to any of them.  Any thoughts on either of the above Muff variants?...the Tall Font has me particularly intrigued, as a fair few of the youtube demos of clones (and originals) sound good.
