After years of using a standard 58mm-or-thereabouts tamper I finally switched to a 58.40mm tamper to fit my 20g VST basket
Holy puck Batman! What a difference. No change to dose weight or distribution technique, but massive difference in the pour and espresso quality. The tamper base now fits with surgical precision. No vacuum issues though. I'm using a simple vertical, single tamp. No nutation. No polishing. Key observations:
Super pleased! Even better improvement than expected

- Longer time until coffee starts to pour
Visibly more honey-like
Much, much more consistent flow. Old tamper sometimes produced watery flow indicating channeling
Denser Crema
More intensity of flavour and richer body
Super pleased! Even better improvement than expected
