K, I took your ****** ass off ignore for a min to see if I can help.
It could be a number of reasons why your shit is coming out choppy.
Something may be forcing the vector elements to rasterize.
Could be if your using certain blending options, or filters.
Also, too many layer adjustments will make pentool look choppy as well.
ie; overuse of gradients, Vibrance, exposure,contrast etc,etc
Best results for vectoring are always produced with Illustrator because it's not a pixel based program,
but you can even compromise the integrity of that quality by not exporting/saving in the right format.
If you're usung vector elements in PS just be careful how you use your adjustment layers..
Also, make sure your dpi isn't any lower than 72 before you start a project.
