The Dwyer DM 4 is a good choice. Some builders have used surplus Viper 640 with the inner sleeve pulled out to lighten it and get better bending. Ive attached the rules with the mast information

i used a viper 640 aluminum mast. I removed the inner aluminum tube out and cut off from the bottom, to get the needed length of mast. converted the mast from a single spreader system, to a double spreader system. I may have the spreader lengths and Dwyer dimensions and spacing of their mast for cabin top setup on my link.
PM me with your email address, if you could use the diagrams, if not in my link. Saved a much of information over time.
