Alright, /out/, i need your help

I'm torn between these 3 backpacking packs right now, Volt 60, Talon 44, and Atmos 50, and would like some expert advice from y'all about which one i should purchase since im a bit new to the /out/ life and i dont really know how to make these decisions.

looking to take 2-5 day trips in 3-season weather (no winter...yet) and have heard that smaller bags are better since they make you smarter about packing, so im leaning towards the Atmos 50 since it's the middle of the 3 sizes

all of them are roughly the same price so thats not a huge concern, but i wanted to know what people here thought or any personal experiences/preferences i should be considering

thanks!
