I've been wanting to try the Head Kore 93. Love the 105 but I hear they do not ski the same.
I liked the Kore 105, but I loved the Kore 93 and have a pair on order for next season.
I have seen, but not skied the new for 2019 Kore 99. It has a lot more shape (side cut) than the Kore 105 so the feel on hard pack should be different.
