I tried the Anders Erickson version and it was great! A bit too sweet so I'm going to give this (above) version a try next. However, I don't think I'm gonna skip the Angostura Bitters.
Adding his recipe here:
1.5 oz. (45 ml) Rittenhouse 100 proof Rye Whiskey
3/4 oz. (22.5 ml) Cocchi Vermouth di Torino
3/4 oz. (22.5 ml) Bénédictine DOM
4 dashes Peychaud's Aromatic Bitters
4 dashes Angostura Aromatic Bitters

I found the strawberries barely noticeable, the Campari is still super dominant. I might try again with more strawberries and/or less Campari.

This was unbalanced and lack sweetness. I used 190g of ice. I'd try this again with an additional sweetener and less ice.

It's a true classic I'm always coming back to.
Such an excellent drink.
