this is what I was looking for thanksI'm assuming you mean Blacksand on the outside and Kryptonite inside, but if not don't use Blacksand inside, you're wasting it. It does nothing inside.
What's the duro target you're shooting for? The directions just give you how much drop per ounce.
The directions are 3 to 3.5 points with 1 ounce in an 900, so you can judge how much you need. Btw, 30cc is essentially 1oz.
Kryptonite typically you'd run 60-90cc. 60cc you'll generally end up around 54-56, 75-90cc you'll end up around 52-48.
What track is it, and you can get more detailed info.
Yes, the greasiness is how it builds bite. Use straight Blacksand during the week, then use something like Orange, Sapphire, or Quick Dry, or Acrysol or some other pre race wipe at the track to cut the greasiness.
