TBH a Z1000sx wasn't on the list, I just happen to pass one the other day and though "hmm, that looks interesting" - as a 2nd bike I'd want a v-twin, but would possibly settle for a triple - but deffo not an IL4. Nothing wrong with having a fondle of a few bikes on a boring weekend
The torque curve is even flatter than the Street Triple and I can tell you it feels very similar to a Triple to ride.
