Not enough overlap
I've used the torque nuts several times. They work great in the horizontal, but vertical cam placements are more harder to find because the change in sizes don't overlap well. Don't expect to be able to cam these in every vertical crack, even when they are uniform. The sales pitch is that there are only four sizes that cover the same ranges of other curved hexes with fewer pieces. That's bs. They need to add some sizes in between. Oh wait... you just want to hear about how great they are and why you should buy them. Sorry. They are fun to place and look cool though. I count on my tricams ten times more.
