Slim Avocado?

I have had them, I never really noticed a difference.... I usually just make guac with them though... i'd say give it a try and see what you think

Here's what I found Googling.. The Slim are grown in FL & the Haas are grown in Cali.

Apparently it's merely a marketing ploy to get us to think they are lighter but they are actually quite a bit higher in cals because of the larger size.

What’s the Difference Between California and Florida Avocados?
Just how quickly those calories add up depends on what type of avocado you have. Here in the U.S., the two main varieties of avocado are usually referred to as California and Florida avocados. The California avocados (also known as Hass avocados) are the ones with the dark, pebbly skins. The ones with the smooth green rinds are Florida avocados.

How Many Calories Are in an Avocado?
One obvious difference is that Florida avocados are larger than the California variety and so they are quite a bit higher in calories. An average-sized Florida avocado has about 300 calories versus 200 calories for a typical California avocado.
A not-so-obvious difference is that California avocados have a higher fat percentage, which makes them higher in calories if you’re measuring by weight. An ounce of Florida avocado—which is a piece about the size of a golf ball—has about 33 calories, whereas the richer California variety packs about 50-calories per ounce (or golf ball).
This can all get very confusing when you’re trying to look up nutrition information for avocado. In order to get accurate information about fat and calories, you need to be sure that the source is referencing the same type of avocado as you’re eating.

What’s a “Lite” Avocado?
Just to make things a little bit more confusing, you may have seen something labeled a “lite” avocado at the store. This isn’t really anything new. It’s just a new marketing spin that some clever Florida avocado growers came up with. Seeing as Florida varieties are lower in fat, they thought they’d play up that advantage by rebranding Florida avocados as “lite” avocados. But buyer beware: Ounce for ounce, Florida avocados are lower in calories, but you have to remember that they’re also twice as big. If you’re going to eat the whole thing, you’d actually be far better off eating a California avocado.

Which Kind of Avocado is Better?
In terms of flavor and texture, California avocados are richer, creamier, and more avocado-y. They tend to make better guacamole, for example. The one time when I prefer the Florida variety is in grapefruit and avocado salad, which is, not surprisingly, a classic Florida recipe. In this dish, I think the Florida avocados work better because they hold their shape much better and don’t get slimy.

Why Are Avocados Good for You?
Adding avocado to your salads can vastly increase your absorption of nutrients from the vegetables in the salad.In addition to being rich in monounsaturated fats, avocados are also a good source of vitamins C, E, K, folate, and fiber. Not only are they nutritious themselves, but they make other foods more nutritious as well. As I explained in a previous article, adding avocado to salads can vastly increase your absorption of nutrients from the vegetables in your salad. Nice trick, huh?

I suspect the variety is the Florida avocado and since i live in Florida, and am in love with Hass variety, I was always dismayed that the Florida type would always be on sale & cost less than the Hass. I love the creamy (fattiness!) of the Hass, and it's buttery/nutty flavor. Of course it does have more fat. The Florida avocado has a green skin that is smooth and doesn't turn black upon ripening. It tends to be bigger & taste sweeter, is less creamy (imo) and has more moisture which i guess is also what makes it seems more watery than creamy/fatter and therefore "slimmer."
