Out of them two I would go the Python's but IRC tyres certianly have a place, god knows their well cheaper.
I would look at other tyre manufactures as well, Michelin make great tyres, which I have used with great results. Kenda also make some great tyres, Ok,Ok,OK! Y'all going to say that their cheap crap, but their higher lines of tyres are great; I'm not sure of the importer to Australia though, so you may have trouble finding them.
The Hutchinson tyres are a pretty soft compound, I wouldnt go riding around on the road or path too much, or they'll be slicks in a few months
But lighter tyres will make a great inprovment in bike speed, less rolling weight ya see.
