Painting straight lines using Brush tool an Shift+stylus without fade out - how to?

[Tonic]

With mouse, you don't have a fade out effect. With stylus, it seems that Photoshop uses the lowest pressure (which appears as you touch stylus to tablet) and.. you know. This is something very simple, yet I have no idea how to solve it.

If you have shape dynamics turned on and the control set to pen pressure, then as you have seen it will fade out the stroke according to your "clicks". So if you press hard when you start the stroke and hardly touch the tablet on the last click, your stroke will fade out to match the pressure you applied.

The only work around I can think of, is to turn off Shape Dynamics then your brush will work as if you were using a mouse.

or turn off pen pressure dynamics on opacity and or flow

I think I need to clarify something, as you can make straight lines with Shift in two ways. What I meant, is this:

1). "Click" brush anywhere, it might be a dot, then release stylus
2). Hold Shift and click anywhere - at this moment a line between those two points appears.

In that way you can create polygonal figures.. hope you get it :)

Disabling Shape Dynamics didn't help, but disabling Other dynamics did.

But I thought there's a way (a special hotkey or something) to bypass it, instead of switching to other brush or disabling Other Dynamics every time you make a line, and those methods are a bit tedious.

I usually just reach over and use my mouse when I need to draw straight lines like that, or if I don't care about using a brush I'll press U and use the line tool (make sure it's already set to draw pixels and not paths though).
