I have mostly used gel shaving cream from a can. Or sometimes, the foam. And the disposable cartridges. Never again. That pre-shave gel and the shave lather with the badger brush along with the safety razor is f'n awesome. Feels and smells great.
And you are correct about wanting a heavier handle. It's best if you can go in a store and get the "feel" of their different razors. And yeah, you do just let the weight of the razor do the work. I was really scared about cutting the shit out of myself, but went slowly the first time just to get the hang of it. Didn't nick myself once, and got a really close shave. Each time since, I've been getting a little quicker as I get used to it. It's expensive to buy all the stuff to get started, but worth every penny, imo.
