Go heavier late and it is lovely, more earthy and spicy, more like an English hop, but with a higher AA. Wouldn't compare it to galaxy. It's got fruitiness, but no grapefruit or passion like galsxy.
Did a smash with English ale malt and topaz and it was delicious, after a small wait. I'm probably imagining this but I find higher alpha hops are harsh early, but that harsh bittering fades really fast....like in less than 2 weeks. My experience only extends to galaxy, citra, por and topaz.
Anyway I've just sampled a stout using topaz (ran out of goldings) and it is very very nice.
Gonna get another half a kg tomorrow for more experiments.
