I have modified a lot of my feet to suit me.
I'm getting a lot of PMs from posters asking if I'm afraid of ruining the feet by modifying them and I shouldn't post doing it as others may ruin theirs. First answer: If I ruin a foot I'll buy another one. In fact I have ruined four free motion feet before I got it the way I wanted.
Second answer: if someone ruins their foot they can buy another or if they can't, don't modify it in the first place.
