As you gain experience you will develop a style and a preference for gear that suits you. Some people swing toward the super ultralight end of the spectrum and trim the margins of their maps, eat food that requires no cooking, etc. Others will carry 60 pound packs for an overnighter.

The Gemini is a good middle of the road compromise. It's not superlight, but it is definitely not ridiculously heavy. You are bound to get substantial use out of it.

If I want to pare my shelter to an acceptable minimum, I go with a bivy bag weighing less than a pound and pair it with a tarp also at a fraction of a pound. Properly situated, such a combination can be surprisingly storm proof and comfortable. But I usually carry something a little heavier and a little easier to pitch.
