I switch between forcing gel and preventing gel. With my milk, beer or honey soaps, I prevent gel by popping it in the freezer as it's all too easy for them to overheat and I don't want a messy soap volcano to deal with. I like the ungelled look, especially for milk soaps, as it does look nice and creamy. For other soaps that don't contain sugar-y additives, I tend to try and force gel along a little by insulating with a few towels - if they're going to gel, I'd like them to gel all the way! I do prefer preventing gel though, as it's just plain easier. I actually just made a batch of soap using a new FO, wrapped in a towel like usual, checked on it after 30 mins and it's bloody roasting hot with a big old crack down the middle! So into the freezer it goes.
I feel like there are just less problems that go along with preventing gel, than forcing it. I've heard about CPOP, which I'm curious as I really hate to see a partial gel - nothing wrong with it, it just doesn't look good to me.
