The CN isn't especially thick behind the edge, so carrots shouldn't be a problem. What you describe may be caused by improper sharpening, by not respecting the blade's asymmetry.
The proportion 60/40 does not refer to the angles but to the degree to which the edge is off-centered. A 50/50 has the edge in the center, a 90/10 has the edge very strongly off-centered to the left, with an almost imperceptible left bevel.
Normally one would advise to stick with the factory edge, and only change it when an improvement is wanted. You may follow the factory edge with the sharpie trick, or by verifying the scratch pattern.
Without handling the blade I can't tell you how the angles will turn out. Common values though are some 10-12 degree right, and some 15-17 degree left. This is a reasonable starting point. If still steering or wedging occur you may change accordingly, by thinning one or both sides and change the angles and the bevel size. See post nr 109 by Geo87.
