Hi Greg. I agree. I don't plan on throwing my metal tapes to the wind. Red Tape is not a wonder-tool, no tool can be, but it does have certain applications it works well for. I have Starrett metal adhesive tape (which I love) on a couple of jigs but never cared for the price or limiting factors (as you mentioned, buy a 6' roll just to cut off the first 1.5")- especially if it's just a quick make-do jig that I may use for one project then toss.
Thanks for the valuable comments.
