It's tough to go lighter in weight. Once you get used to it, though, you can really fly. For me, I like to use the bounciness of Cherry switches to "help" my fingers back up. There's less fatigue this way and it helps me type faster. Heavier switches, especially ALPS, feel like I need to slam the keys. I certainly felt the same way you did when I first tried Cherry browns. These days, anything else is almost too heavy.
