Used Lemon Hart for the rum, Disaronno amaretto and went for 22.5ml of lemon juice. Sweet and bright! I decided to ignore the sugar syrup, but I would go for 15ml of lemon juice if I had used another kind of rum. I ignored the garnish because I'm lazy, but I can imagine how the cinnamon would work here, so maybe I'll just grate some on top next time.

I put more lime juice and rum in it, and amaretto still sticks out for me

Another keeper when you want a smooth sweeter finale' cocktail. Very nice indeed.

Just started getting into cocktails, and this has been a helpful guide, but I never felt the need to comment until now. I had just got amaretto and was deciding which cocktail to try. I had narrowed it down to this and the french connection/godchild. I somehow got confused, and though I decided upon this one, I used cognac instead of rum! Not a total disaster, I guess those two go together in the other ones, so it was nice enough.
I did end up trying this one, I prefer it! (No syrup in either)

Used a locally produced dark-ish rum with a pretty strong character, and no cinnamon or rim of any kind, which it definitely did not need, IMO. The rum I used was strong enough to balance the additional sweet from the sugar syrup pretty well. Overall I liked this one, and I'm glad to finally find something to use amaretto in that isn't overpowered by its flavor. The rum/amaretto combo works really well.

definitely did not need the added simple syrup imo

Myers's and Gozio was a fortunate combo. Didn't apply the cinnamon garnish but, wow, does this already have a peculiarly strong sense of cinnamon going on. Somehow, I did not find this drink too sweet... But to apply the 'Daiquiri' tag to this?!?

I reduced the sugar but it was still a little too sweet for me. Next time I will try upping the lemon as well. Me and the other “discerning drinkers” in my household enjoyed it a lot, nevertheless. Agree that it goes down a tad too easily!
