I have been following the comments about composite staples and stapler with great interest. I do not have a compressor and besides would prefer not to have to trail an air hose around. Yesterday I ordered online from Duckworks the Rapter manual stapler along with a box of 14mm (9/16") composite staples. I will soon begin construction of the ECO 6 and hope this addition to my toolbox will help speed the work. I will report back once I have some experience with it.
