Things I liked:I think this upgrade solved all my questions! Great idea and it works!!! Things I would have changed:None What others should know:I had a problem with loosening the screw on the trigger and contacted service and they told me what not to do. I think I have found out what to do. I used a vise grip (needle nose) and squeezed the trigger right next to the screw then I rotated the screw which would not move previously!
