Can I go straight from the On Cloudmonster 1 to the Cloudmonster 3 and skip the Cloudmonster 2?

Yes, but going Cloudmonster 1 to Cloudmonster 3 means taking one change in a single step: the Cloudmonster 2 is where the ride moved. Drop holds at 6 mm, so the difference is foam and fit rather than geometry: Helion superfoam to Dual-density Helion superfoam.

How much did the weight change across these two updates?

0.7 oz on in total, 9.7 oz to 10.4 oz in a men's US 9. The Cloudmonster 2 took it to 10.4 oz first.

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

On paper it splits them: 10.4 oz against 9.7 oz for the Cloudmonster 1 and 10.4 oz for the Cloudmonster 3, on a 35 mm heel and a $180 list price. Whether that is worth chasing depends on what the Cloudmonster 2 update actually did, which the section above works through.

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

Heel stack went 30 mm to 35 mm, by way of 35 mm on the Cloudmonster 2. Drop held at 6 mm throughout, so the extra foam sits under both ends.

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

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

Or buy the Cloudmonster 2 instead?

The Cloudmonster 2 is worth a look only if you want the ride it introduced, because that is the update that changed the shoe. Buying it to soften the jump does not work: you would be adapting to the same change either way, just at an older spec.
