Yeah, just a half-dozen swipes using a 1/4" round file reduces the long spline so it slides onto a UG freehub. The metal is easy to cut with a reasonably sharp file, as long as it's held in a vise.
I myself only prefer HG cogs for use with indexed shifters.
For friction shifting, I prefer the reliable audible feedback of UG and Suntour cogs which prevents me from experiencing random ghost-shifting from a misaligned gear selection.
Whenever the noise of wind, traffic or a surrounding peloton prevents me from hearing an HG shift event using friction levers, the non-HG cogs seem like a necessity,
