The Greenland paddles are slower to accelerate, but are said to cruise nicely with a slightly faster stroke rate. They are held lower, with less shoulder movement required. The power comes from the core. They are easier on the shoulders, a real consideration for paddles in their 60s.
I'm very happy with my first Festool. More will folow. That Hk-55 Track Saw looks like it needs a home. My grandson actually got to be the first operator on my new sander while I set up the strongback for his new kayak build.
