The AZ-EZ is just that... EZ! It may look like a spider on steroids in the picture, but it is simple to use, place the vanes in and spread glue and pull it up to shut and your done! I also bought a Jo-Jan, and only did so because I wanted to try the nap quick spins, it is easy to use, but it is only one at a time! Also, you need to have some off set or a helical if you plan on shooting B-Heads, I may be wrong, but I do not think there is any head thatflies great with 100% straight vanes, almost all have some offset, 100% straight only works with field tips. Have never tried 100% straight my self, just what I have been told from the old wise men on the corner! LOL!!
