I am also highly sensitive to wool, in direct contact with my skin, but I'm going to buy 1 skein of the alpaca yarn to see if the stories of it being hypo-allergenic. I'll knit up a swatch and pin it to something so it against my skin for a while. I'll report back with my results. Worst case scenario is having to breakout a tube to "Cort-aide" to stop the itching. Heaven knows I have plenty here at the house.
