I'm curious to know people's thoughts on knee locators, as I'd never worn pads with them until my most recent set. I thought that it would be a large improvement. However, due to the slightly too small nature of the pads (the danger of buying off the internet more cheaply without trying on), I have found them substantially less comfortable than my old Woodworm Premiers without a knee locator.
Basically, just want to know how other people see them. Essential? Beneficial? Indifferent?
