I have the honda wheels on mine, I can't say I've found them an issue at all.
I can put them in drop or lift position on my own without problem, whether on water or on land, pretty sure I've done so too with the nipper in the boat.
My mates dad (aged 70+) has a false arm, he too manages the wheels on his own. I believe he put a locator on the shaft though, and ground away the mount slightly.. See pic
