I use the leather key pads from Depo Book. They fit the Diamante great, and it's the most comfortable touch. Now that I found these pads, I'll never get anything else.
Yes, Ilove to have cushions on my keys, too. Also I have a few trouble spots where I double up on the key to make it easier to hit. LIke my "A" key. For some reason, my thumb misses it, so instead of "like" I get "alike" etc.
