RE: Shaft zincs

Since I changed from the egg shaped shaft zincs to the donut shape, they have stayed on much longer. The lack of meat around the screws on the egg shape caused them to fall off when only 10% gone (or so), while the other shape hangs in to 40% gone. I haven't seen the donuts any worse than 40% gone, and I have lost some before the next haulout, so I can only assume they don't hang in much past 40%.
I have seen several brush systems, but they all look pretty Mickey Mouse (no offence intended Minnie) and I have no desire to try one.
