I love the 8.5 by 24.5in much more than the Omnigrid I was using before. I find the markings a lot easier to follow and it slips less. When I need to replace any more rulers, I plan on buying Creative Grids. It's more expensive than buying the Omnigrid or Fiskars at JA with a coupon but as my eyes get older it's harder to see the markings on the others.
