I love both the Mooer Shrooms and the Mooer Candy toppers. On my FC12, I have Shrooms along the bottom row and Candy on the top row. The reason is, I originally had Shrooms on all 12 switches, but noticed that it was more likely I would activate a top row switch if I missed a little when hitting a bottom row switch. With the Candy ones on the top row, they have a steep side (unlike the roll off side of the shrooms) which makes it harder to activate that switch unless you are coming down from the top. I LOVE the way the clear versions accentuate the colors of the FC12 LEDs and considering I am playing barefoot most of the time, something along this line was definitely in order for me. I have not tried any others, but don't feel a need to as I am very happy with these.
