Trail runners vs Tassie conditions - thoughts?

Hi all,
I was wondering how fellow Taswegian ULers (and those from elsewhere who have bushwalked here) have found wearing lightweight trail runners on our tracks, particularly when it is wet, cold and/or very rocky?
I'm mulling over ditching my well worn Goretex Scarpas... they've been rather good boots and still have a bit of life left in them (despite losing an argument with a chainsaw at one point) but they weigh 850gr a hoof, and if the adage of '1KG on your foot is worth 5 on your back' is true, then that's a shedload of extra weight I'm carrying around. There's also the question of waterproofness vs dry-out time; because I usually fish most places I hike, and invariably end up in the water a bit to retrieve or release trout, I tend to get the boots wet eventually and being Goretex/suede, they don't dry particularly fast.
I've read up on the all the current theories about embracing wet feet and using fast-draining shoes and quick drying socks to let them dry out 'on the move'.... that all makes sense and to be honest seems vastly preferable. On the other hand, walking through ice cold water or even snow could be at best very uncomfortable - or at worst, potential frostbite territory - if your socks and shoes don't dry out because it's too cold/wet. Obviously I wouldn't be silly enough to take such shoes on a winter/snow trek, but even in otherwise perfectly suitable warm summer conditions, random blizzards are a genuine possibility up the highlands/plateau.
The other big question mark for me is snakes. The combination of heavy Scarpas and knee-high gaiters is pretty confidence-inspiring bashing around the Western Lakes scrub in the heat of summer. I'm pretty careful about watching where I step and tend to see snakes well before I come near them, but figure it is only a matter of time before I manage to step on or very close to one. I know Tiger fangs are easily thwarted even with light materials but those mesh uppers on most trail runners aren't confidence inspiring, especially if you've got equally thin socks underneath.
An alternative to the typical lightweight mesh runner (ie. Inov8 Rocklite 315/295 etc) I'm considering is a lightweight Goretex boot aka. Roclite 286GTX. A bit more material, more waterproof/resistant but still a fraction of the weight of the Scarpas. Price is also pretty good too... in fact I could see myself buying a pair of each, the boots being the 'highlands' option, whereas the shoe-style runners would be for East/South coast trails.
Anyone got any experiences they can share?
Cheers, Ben.
