This set is a bargain! TCUs are awesome and really affordable. Narrow head width, so they'll fit in small pods. Flexible enough to work in horizontals. Beafy looking cam lobes inspire confidence. Metolius gear is always bomber.
They're not quite as flashy as BD C3s, or quite as flexible as aliens (but they don't cost 70 dollors like the C3s or have MAJOR safety/quality control issues like CCH)
BD C3s or Aliens. I have two DMM 4cus in the same size as the blue and yellow TCUs and I wouldn't recommend them - I always reach for the TCUs first.
