How to improve motions around the kit

[Soundwaver]

Hello!

Sometimes I feel uncomfortable when playing fills around the kit/toms.

When I am playing rudiments on the snare or on the practice pad I can play fast and solid but when
I take it to the next level and start to apply it on the toms it feels almost that I am loosing the balance.
Do you have some great exersice that can improve my motions around the kit?

Thanks!
