Kingy,
Not sure why you say you don't agree with me re. the Cub's limits - it sounds to me like we agree!
PA18 has a max demonstrated x-wind limit of 12kt, but a good, current pilot should be able to handle about 20kt like you say (less if it's gusty). When I was very current on PA18s, I was perfectly happy in this kind of wind.
The PA28 has a max demonstrated x-wind limit of 17kt. Because I've never had a period of really intensive flying in it, my personal limit, even when I flew it regularly, was around 17kt. But a good, current pilot may be able to handle much more - probably around 25kt.
The point that I'm trying to make is that my limits in the PA18, when I was current on it, were higher than in the PA28. This is nothing to do with the limits of the type (which are actually the other way around) but purely to do with my currency. And I suspect that the reason Bloke prefers low wings in a cross-wind is purely because he is more current in them.
