I don't use a profile, but I've had a lot of questions about stick scaling.
For CH gear, and old wise hands you can be pretty aggressive, some max scaling across the board.
For Saitek, Logitech or MS Sidewinder sticks you might want to try something like this for pitch.
This will give you finer control near the center.
Roll scale can look more like this
or indeed even more aggressive, as roll will seldom stall you.
Having more input will make your plane roll faster, with less joystick input required.
Rudder scaling could look something like this
Note the higher deadband setting for the rudder. To help prevent accidental input.
That is not to say you need to set yours like this. Its just an example to give you a place to start from.
How much or how little will depend partially on your hardware, how sensitive it is.
And partially on your hands, and how smooth you are.
