Can I go straight from the Saucony Guide 17 to the Guide 19 and skip the Guide 18?

Yes, but going Guide 17 to Guide 19 means taking one change in a single step: the Guide 19 is where the ride moved. Drop holds at 6 mm, so the difference is foam and fit rather than geometry: PWRRUN foam with CenterPath geometry and a PWRRUN+ sockliner to Softer compression-molded PWRRUN with CenterPath geometry and a PWRRUN+ sockliner.

How much did the weight change across these two updates?

0.3 oz on in total, 9.4 oz to 9.7 oz in a men's US 9. The Guide 18 took it to 9.6 oz first.

Is the Guide 18 the better buy than either of these?

On paper it splits them: 9.6 oz against 9.4 oz for the Guide 17 and 9.7 oz for the Guide 19, on a 35 mm heel and a $140 list price. Whether that is worth chasing depends on what the Guide 18 update actually did, which the section above works through.

Where does the Guide 19 sit in the Guide lineup now?

It is the current model, two versions on from the Guide 17 and the newest one you can buy at full retail.

THE SHORT ANSWER

Two updates and 2 years separate the Saucony Guide 17 from the Guide 19. Net change: 0.3 oz heavier, a new midsole. The Guide 19 is where the character changed, and that is the update Guide 17 owners notice first.

Or buy the Guide 18 instead?

The Guide 18 is the value play if you find it discounted. It carries most of what the Guide 19 added while selling as an older model, and moving one version at a time is the smaller adjustment.
