Currently I use the Spurlock system but a fellow tech once loaned me his Bushmaster. I did one half of a keyboard with the Spurlock system and the other half with the Bushmaster system. I timed both halves and the Bushmaster was slightly faster, about 3 minutes for half a rail. What I didn't like was that I wasn't able to be sure how much glue I had in the key mortise. With the Spurlock system the glue is applied to the cloth in full view. With the Bushmaster, the glue is put into the mortise and its hard to see how much glue is in there. At the end I decided to stick with the Spurlock system, because I'm willing to sacrifice perfect uniformity of depth for perfect uniformity of glue. Then again, maybe I didn't have a good enough method of applying glue to the mortise.
