Rooster yarn?

Just to complicate my yarn choice further (I'm still weighing up Cashmerino Aran and RYC Cashsoft Aran) I've just discovered another aran yarn - I think it's new. I've never heard of Rooster yarns before. But it sounds lovely - 50% alpaca and 50% merino - Almerino
I've made a jumper with an alpaca mix yarn before and it's bloomed quite a bit - also very very warm, so possibly this yarn isn't the way to go. It's also more expensive even than the Cashsoft...
