My next PSB system I want an all spikey hairstyle...

So what hairstyle should I order so the hairs in the front will point upwards easily?

Because I've experienced the hairs in the front are the hardest part to stand up.

I've read some people order flatback so the hairline at the front will stand up very easy...

Or can I specify it in my order that they inject all the hairs in an upwards direction? But not the hairs on the sides

ofcourse or i would get blending issues. Thx for the help.
