straight sculpt relative to stroke

[system]

Hello everybody, using rake brush with an alpha. In both cases I did a straight down stroke, but the sculpt is different.
How do I get my sculpted detail to follow more of the brush stroke like the one underlined in green (when i stroke brush straight, id like it to sculpt straight), the one in red gives weird curves in some places.

I think you might need another Divide level or 3. The Rake Brush has an alpha, that alpha is fairly low rez. The subtool is also low rez. These combine for jagged strokes.
At least, this is what it looks lie to me.
