7g per side is definitely a little on the light side, especially for learning. The lighter the set, the more precise your timing has to be, which makes getting the feel for it a decent bit harder.

I'd aim for at least around 17g for the set, preferably ~20g. The Mini Hydras (~20g) will do you so well, imo. They're a fantastic weight not only as a first set, but you literally cannot outgrow them. They're just as suitable for advanced tricks as they are for learning, which is why pros love them too. If there's one set I could pick for an all around 'best' set for everyone, I would say the Mini Hydras are it.

The Modern Standard Heavy is also a good set, but it comes in at 28g which is heavy. Just like a set that's too light, too heavy can make getting the feel for it more challenging as well, plus they tire your hands out a lot more than a mid weight set.
