Having said that, I don't think its a very good idea to launch with
airmet ZULU along your route, but there may be some exceptions (like
when you have VFR beneath you above the MEA), or you have a pilot
report from a pilot who was just in it and not only didn't he pick up
ice, but he doesn't think there IS icing in those clouds.

How do you know how good a judge of ice that anonymous pilot who's
flying a different kind of plane than you is?

I think they should make icing a "percent probability" and when the
probability is greater than some figure (say 30%) then it's a no go.

Well, is it 30% of picking up ice (but it would be everywhere) or there
is ice in 30% of the cloud? And which way is out?
