Sweeter sour cherries tree for Vancouver/Surrey

I got couple Dwarf Sour/tart cherries from Sask nurseies, Like Romeo
Anyone have them here, and how well they grow in our climate?

 

I have a dwarf 'cupid' that grows well but has yet to produce fruit; I got it in 2015 when it was only a couple of feet tall but now that it's about 5 ft so I'm hoping it will produce soon - it flowers nicely.

 

Thanks for your reply, I have Cupid as well, they are very small pack size 6 inches tree in pot but grow quickly, look forward to hear your feedback on its figs taste in Vancovuer area.
