I just ordered a 58.5 mm Normcore tamper and, as it comes with three different springs, was wondering which spring you ended up using and why - if you've had your tamper for a while. I understand the principal behind different tamping pressures, and certainly intend to try each spring and experiment a bit, but thought it foolish not to solicit the advice of this large and experienced community... Thanks...

they aren't super easy to tell apart at first glance. i wish they color coded them. i had to stack them up side by side and visually gauge which was which.

the one that came in it was too light compared to what I'm used to and I switched to the 30 lb.
