I bought the Ninja and it now my favorite belt. It's slim, clean, simple, elegant and comfortable. However, I did not like that it did not sit evenly on my pants because the T on the end of the strap protruded 1/4" behind the buckle, and the tucked strap rode over this bump. I therefore trimmed the T and turned it into an L that is still held into the slot. This reduced the bump behind the buckle significantly. However, I am still considering notching the back of the slot so that the L will sit flush into the buckle. This way the tucked strap with sit against the whole back of the buckle. If the buckle was 1/8" or 5/32" the slot could be notched deeper. I look forward to buying a few more Grip6 belts! thanks
