Ingrid, I haven't tried a true Merino, only the Merino Frappe. I haven't had the courage to spend the money on Alpaca yet, but I have had the chance to drool over it at my lys. I will have to try them both. As for the Addi turbo needles, I haven't even seen them before! Did you get them at your lys or online?
