I used to work in a store that sold the Dynaflex (Eastern Mountain Sports). We'd use 'em all day long and boy would our arms be sore! I bet they'd be great for building up the wrist and forearm muscles to make it easier on those one handed, reaching cuts with the 200T. They are kinda expensive for a forearm trainer, but they're fun!
