This is a variety I've had my eye on, but I haven't tried it out yet. I don't know if I can bring myself to buy any more hops right now, but I've had a thought to do an all-Aussie hopped IPA with Galaxy, Summer and Topaz. The earthy, English hop thing is keeping me a bit gunshy. I've had a few other hops that have a fantastic aroma, but taste like a fruity Fuggles. Which basically makes them too fruity for an English IPA and too earthy for an American IPA/APA to me, so I only use them for flameout/dry hops.
Keep us posted if you try them.
