I've added some new information to the CTKv4 article, including:
- A note on the size of the wrist cuff
- Explanation of the arm-wrap half hitch directions
- Some tips for tying on those with large breasts
- A section of links to related work
Ropeboi also pointed out to me that I failed to mention in the list of benefits of the split stem how much more comfortable it makes this TK for lying on your back in! BondageNexus posted a great photo illustrating this.
