I tried sending this out two nights ago, but my e-mail server has been giving me fits... so.... I do have a concern with turbo on the arm at the lower angles - it already goes really fast down there. More precision (slower) control of the arm at the higher angles, coupled with mentor or driver calling out Tetra On Board light on/off might help when we are placing the tetra on the goal; its worth a try.
