The "Reel Easy" is a 'bump' head. It contains a length of line that's replenished when you tap the head to the ground. The "Pro" uses a "fixed" length line. These come precut and are manually inserted into the head. It's usually heavier duty line and lasts a bit longer.
What is the best way to edge with the trimmer between mulch and grass?
Verrrrry carefully! Safety first: eye protection, hearing protection and long pants and leather boots. Sure, you can wear shorts and flip-flops if you don't mind your legs and feet getting lacerated. Dirt and rocks WILL fly up in you face in the vincinty of your eyes and listening to any loud sound for a sustained period WILL damage your hearing. It's not worth it.
To edge, you have to rotate the head of the trimmer 90º so that it is moving vertically and away from you. Some units allow you to do this on the handle. If yours doesn't then you have to rotate the whole shebang.
By observation, you can gauge how close to go to the ground and by angling the head ever so slightly, you can, with practice get into some tight spaces. Edging will eat a lot of line.
