I am looking for a dedicated premium rip blade for my 3hp Sawstop as I have a bunch of projects comping up utilizing 8/4 hardwoods and found something interesting on my search. I always thought 24tooth dedicated rip blades had a flat top grind such as what Ridge Carbide, CMT, FSTool or Freud sells, however, I noticed companies such as Forrest and Tenryu sell their 24 tooth blades as rip but have ATB configuration.

Why aren't all rip blades flat top grind? Which configuration will give me a cleaner rip cut? Is there a difference? I am not a production shop nor do I use a power feeder.
