It's a matter of preference, sure, but if you use the 7tt feature yourself, give volumouse with increasing steps a go, you'll never go back to the fixed steps setting again, it's great from the first time you try it.

No, not faster, what I meant is that at higher volume, every scroll has a larger impact. If volume is at 5% one scroll = 2% for example and when volume's at 95%, each scroll changes it by 6% (random example values). 

This way you can precisely control volume at low sound - when precision is needed - and ramp it up quickly when you need it loud, and also kill it almost instantly.
