Quite a difference I'd say, HD. You say radars in the UK don't show wx, I say that some of them do (if the controller chooses to look at it). Having used both, not having the ability to wind in the wx when there is lumpy stuff about is a real disadvantage. If the controller can look at the wx he or she can offer wx avoidance advice. Your post suggested that this doesn't happen at all in the UK.
