I like FLV Sweet Mango at 1% and FLV Ripe Mango at 0.5% (see my
Tropical Yogurt recipe).
FLV Sweet Mango isn't a "sweet" sweet. It's more like the sweet of a nicely ripened mango IRL. FLV Ripe Mango is a ripe mango, just not as ripe as the other, less sweet more mango. Each mango lacks notes the other has. Paired together = awesomeness. Very similar to eating a freshly ripened mango. Both offer juiciness.
When I've used each on their own I was left with something less than a complete mango.
I've switched up the percentages with both for different mango notes. Like so, FLV SM 1% + RM 0.5% (as noted above) to SM 0.5% and RM 1%. No matter how I change the percents, they always deliver a very well rounded mango profile.
FLV Mango is good but it is not as highly concentrated as SM or RM. SM and RM are ultra concentrates.
At 1% and 0.5% they make their presence well known with nearly every flavor I've used them with.
