does anyone have experience with both of these systems?

I noticed that the Drum-tec trigger system is essentially a roland type cone trigger on a spoke-style suspension that they claim to work specifically with the Roland TD30.

When looking at the DDT truss system, it seems similar that just lays over the bearing edge.

I am concerned with how comparable the performance would be in congestion with the TD30 and Superior Drummer software.

Also of course, i would never want to damage the bearing edges of my DW Jazz series drums.

Thoughts?
Experiences?
Knowledge?

Thanks a bunch guys!
