Can I go straight from the Nike ZoomX Invincible Run Flyknit to the Invincible 3 and skip the Invincible 2?

Yes, but going Invincible 1 to Invincible 3 means taking one change in a single step: the Invincible 3 is where the ride moved. Drop holds at 9 mm, so the difference is foam and fit rather than geometry: Full-length ZoomX to Full-length ZoomX over a stability layer on the strobel.

How much did the weight change across these two updates?

0.8 oz on in total, 9.8 oz to 10.6 oz in a men's US 9. The Invincible 2 took it to 10.3 oz first.

Is the Invincible 2 the better buy than either of these?

On paper it splits them: 10.3 oz against 9.8 oz for the Invincible 1 and 10.6 oz for the Invincible 3, on a 39 mm heel and a $180 list price. Availability decides it: Amazon's Invincible 2 stock is gone in both men's and women's sizes, so it is not a live option.

Did the Invincible get taller between the Invincible 1 and the Invincible 3?

Heel stack went 39 mm to 40 mm, by way of 39 mm on the Invincible 2. Drop held at 9 mm throughout, so the extra foam sits under both ends.

Where does the Invincible 3 sit in the Invincible lineup now?

It is the current model, two versions on from the Invincible 1 and the newest one you can buy at full retail.
