Reuse old pressure plate or buy new???

I need to replace the clutch disc in my car. I currently have a Centerforce II diaphram style pressure plate in it. My question is can/should I reuse the pressure plate and just replace the clutch disc or should they be replaced together? If I replace just the clutch disc is there a certain brand or style that is better? The car is a 73 duster, 400hp (hopefully 500 in the near future) 3.23 suregrip 8.75 rearend. Mostly street abuse, I do a lot of reverse-2nd burnouts. Might see the strip a few times this summer.
