What was wrong with them? I did it to my letters and so far, I love the extra resistance compared to just blue switches.
Personal preference I guess. It probably has to do with PCB vs plate mounting -- I could see liking heavier springs on my Leopold but my poker feels too weird with ghetto greens. Plus I don't bottom out as much on a linear board as I do on a tactile board.
Basically... was trying to get closer to Model M which is what I started on, but found that I actually like pretty lightweight linear switches more than clicky/tactile. smoooooooooooooooooth.
