Can I go straight from the Altra Timp 2 to the Timp 4 and skip the Timp 3?

Yes, but going Timp 2 to Timp 4 means taking one change in a single step: the Timp 4 is where the ride moved. Drop holds at 0 mm, so the difference is foam and fit rather than geometry: Quantic to Altra EGO MAX.

How much did the weight change across these two updates?

0.9 oz on in total, 9.8 oz to 10.7 oz in a men's US 9. The Timp 3 took it to 9.6 oz first.

Is the Timp 3 the better buy than either of these?

On paper it splits them: 9.6 oz against 9.8 oz for the Timp 2 and 10.7 oz for the Timp 4, on a 29 mm heel and a $140 list price. Availability decides it: Amazon's Timp 3 stock is gone in both men's and women's sizes, so it is not a live option.

Where does the Timp 4 sit in the Timp lineup now?

Two versions on from the Timp 2, and already replaced itself: the Timp 5 arrived in 2024. If you are shopping old stock anyway, price the Timp 4 against it before deciding.

Or buy the Timp 3 instead?

The Timp 3 is not a live option: Amazon's stock is gone in both men's and women's sizes. This is a two-shoe decision between remaining Timp 2 pairs and the Timp 4.
