For anyone interested in a better driver for these, I made a Texas Avenger for the D01, it has not been test fitted yet but should work with minor sanding at worst.
You can see all the details here: Texas Avenger "TA" Driver series - Triple channel + Bistro or Narsil + Clicky or E-switch - The Ultimate open source driver!
If there is enough interest (at least 7-8 drivers worth) I can make up a batch of them to sell. Price would be about $17.50 - $20 each depending on quantity.
Or naturally with an open source project like this, you are welcome to do it yourself, please do post your results in the TA thread if you do!
