I have never used Duranos, and wonder about their use on a loaded bike, but given that I have used and ridden Gatorskins for years in the wet and have yet to crash, loaded, half loaded and unloaded, I question your statement.
well, it seems that it's not just me who dislike them for the wet?:

loads more info on google ....
2 weeks ago, I bought another bike for my daily commuting (200+ miles a week) .... it's an older Specialized S-Works and came with GP 4 Seasons tyres .... it's the first time that I am trying these tyres .... so far, so good, but looking at the rear tyre, it seems to be wearing down pretty fast (I've done just over 300 miles so far), and check the pressures every 2nd day. But saying that, we have had hot weather here in the UK over the past 2 weeks (mini heatwave)
so, looks like I will stick with Schwalbe Durano Plus for winter, then switch to Continental GP 4000 S II for spring/summer next year
