I picked one up in .25 recently. Of the JSB kings, heavy MKI & MKIIs I've sorted I only end up with 4 sizes 6.35, 6.36, 6.37, and 6.38. Most of them being in the 6.36 then 6.37, much less in 6.35 and very few in 6.38. Thankfully 6.36 and 6.37 sizes are the most accurate in my Cricket.
I wouldnt say its a fast or entertaining evolution, but could be done while watching a movie or such. However it seems to reduce the # of fliers i have per magazine.
