Mouse config for Rainbow Six: Siege

[Shifty]

Hey dudes. So i've got this fancy mouse but i'm not using it to it's full potential so was wondering if any of you sexy people could help me with mapping the buttons to the actions needed.

I'm bloody rubbish at deciding where stuff should go and the list of actions are as follows;

Ability
Secondary (Nade/Flash/Shield etc.)
Reload

Can't think of owt else atm and any help would be appreciated

Peeking I'm happy with q and e or I can change the mouse feet and use tilt. Vault I use space and melee I use the top thumb button
