Here's some comparison of the DMCG and DMDC. SY had a limited run at knob creek 08' and the DMDC was given some different color coatings, but spec wise, it's the same as the DC.
Here's a DMCG that's been "Banned"
The DMCG was my first SY and I love it. It feels great in the hand and can get scary sharp.
