One other question, do cheesy little bell kits serve as valid practice tools for 4 mallet technique? Part of me thinks the problem is the size of the keys is so small. I have no problem just playing scales and single note melodies with 4 mallets but could the small size of the keys and the closeness of them to each other be causing problems? I shouldn't be complaining since my teacher is letting me borrow it for free until I leave or until another student needs it, but I still would like your opinions.
Here is more or less what I have:
My teacher is now using a MalletKAT pro as his main teaching tool. He noticed the torqueing on that as well, but it didn't seem anywhere near as bad as on the bells.
