I'm going to be using slicks and I need a drive shaft that won't snap.

 

I think there's only one way for you. ACPT carbon fibre driveshaft.
I was thinking of getting one but I don't drag race and I didn't want to spend all that money if it wasn't going to make much of a difference.

However, in your case I think it would be a wise investment....

I would get a MazdaSpeed PPF before a CF drive line.

I have the ACPT CF drive line and I don't think it did anything but make the U-joints replaceable.
