I'm a beginner and have experimented a lot and I've found a couple things helpful. First, I make every recipe in the range of no more than 8oz to 16 oz total fat weight. This way, if it doesn't suit me, I'm not wasting much. Just give it away to a friend with a different skin type.
I also, have experimented quite radically with the SF. Nothing that says you can't try superfat at 15%-20% with any recipe. My other recommendation is to keep it simple, changing one ingredient at a time to see if you can narrow down a what is bothering you. No fragrance, no colorants. Make a formula with no more than 3 fats to make it easy. Start out high on the superfat. It's easy to bring it down if the soap seems to need it. Good luck.
