Thought I would throw out a question I have been thinking about. I believe on my ERYX 2.0 or was it the 3.0 I forget but the front spool outdrives did not use blades . The pin on the driveshaft was larger. My question is why the change?? The dcj driveshafts have a lot of slop on there own and the rate the blades go out it produces even more slop . I am going to be trying other blades like the X-ray ones but right now I am using arc blades as the serpent ones are brittle like the ball cups . But it was just a thought of mine. Personally I liked it better with no blades.
