I have been running my DD for the last week or so and it plows the lines in. One pass just there. It is almost effortless. I tried it with TTechs and it pushed those really well too. Oh and it sounds like a cross between a toy train and a sprinkler haha. They spool up and chuga chuga chuga!!!!!!

I have 3 of Chris' coils, 2 linkage rotaries and 1 DD. Once again Chris has outdone himself and his customer service is amazing. Thanks Chris full review coming.
