I never change pins myself, however as a gift I gave him a Team Magic pin replacement tool. He was happy!
Diatta Collymore will be trying out the Clutch System for the NT1. I will have him report on his findings. They look great and are really a lot lighter than factory and some other after market sets.
If anyone ever needs anything from DnM Tech that I don't have in stock just let me know. I can get for you quickly.
