I've been interested in Delta stuff for some time but never absolutely had to have new equipment but..

I do long cracks as well as chips and for several years now I've not bothered to use a bridge. I just hold the injector with my hand and (run it down the crack or keep it manually positioned over the chip until it's done). I feel that this has given me less gunk to clean up and more speed and flexibility.
So...can this Delta injector be used w/o a bridge.
I've already got a satisfactory source of resin but is anybody using Delta resins for cracks that can give me a report?
Feel free to call. I've got to make a decision on what to buy pretty soon so I don't lose too much time next week getting back in operation.
Also, I don't quiet understand how this "spring activated" feature works in the Delta injector.
