Frozen Rotors Blank or Slotted

[magnumb]

Looking to purchase some Cryo rotors as mine are about past there prime...put over 80,000 hard miles on them and they can no longer be cut. I purchased these from Praise Dyno years ago and i see they are out of business.
Any suggestions? I see Frozen Rotors.com but not sure they are the way to go. Also not sure if slotted is worth the extra $45 as race teams don't even use them.

IMO slotted is not worth it. In fact I wouldn't bother with "cryo" rotors either. Slap some of the good Wagners or Raybestos on there for half the price and call it a day.

Picked up Centric High Carbon for $100 instead of $175 for Cryo.
