A good way to test is to try smaller Rigotti Gold pack (3-reeds in pack).
I can confirm - the Rigotti Gold are fine, a little brighter then older unfiled Rico Jazz Select - D'addario, Vandoren Blue box, and other Rico I tried before.
The numbering is (in my opinion) usually a quarter or half softer than Vandoren (depends on Vandoren type)
They are ready to start in first minutes of playing, it's very comfortable. Consistent, hmm, enough, only some (2 in 10-pack) I feel like more mate, but ... more consistent in hardness and sound "colour" than other brands I played for years.
After playing first half of hour they become softer. I started with Rigotti Gold tenor 2,5 medium, next time I've bought 2,5 strong, using the same 0.110 Slant type mouthpiece. As I was curious, I tried 3 (soft and med.), but I came back to 2,5 strong.
Last 4 years I was playing Rigotti Gold 2,5 strong with comfort and pleasure.
