I use the Otis kit on my 17 HMR. All that was available locally was the 'cheap' micro sized one.
So far so good. As mentioned by a previous poster, the 2" patches that come with the kit can bind in the .17. I use smaller patches - although a smaller square one doesn't have the same cleaning effect as the round ones threaded through the brass eye.
Despite the limitations, I'm happy with the Otis kit. It fits in the range tool box, and it means I don't have to thread tiny little rods together and hope they don't scratch the bore.
My 2¢.
