I've owned or shot every model of Ego, except some of the SL versions. I actually sold my Ego 10 after I got a 7. For me, the newer ones tend to be too long and a touch unwieldy, I love the compact feel of her and the consistency of the shots. Just feels so much better in the hand than any other marker I've shot. The only ones that I like even near as much are my beloved Alias Timmy and a Nexus Ego 06 which I've built from parts over the years.
