Has anyone ever tried this with Old Tom gin? I just did — and found that it added some nice complexity.

A lot of people these days like them frothed up (with egg white/aquafaba etc on top of the pineapple) and served in a coupe a la clover club. I am ambivalent about this, I think it's frothy enough with the pineapple. It's always fun to get a nice head on any drink though.
The drink itself is a bit sweet for me, lemon juice tempers it quite well if you like that sort of thing .
it's nice to have a creative use for Chambord

It was easy to make; tasted good.

Not too sweet! You can taste each of the 3 components. Nice!

Very tasty, good balance, many recipes I found the pineapple too strong but this one had a great balance to me.

I used store bought pineapple juice which was quite sweet (no added sugar though) and it masked the vodka more than most flavored martinis. That can be good since some do not like the vodka taste. I liked the Chambord in it.

Very pineapple forward with a slight raspberry finish at the end. A simple yet very tasty cocktail.

Very tasty! I'm so tempted to put some creme de cacao for a chocolate raspberry flavor!
