Everybody these days is making a version of the STE-100 skill. Me too.
I think I managed to scrape the essence of the STE-100 without too much bloat, and still left enough wiggle room to make it not so mechanical. My version has two modes: strict and casual. Casual is a much better daily driver, but Strict is there if you really need to tighten things up.
Give it a try. It's helped me quite a bit, and I hope it helps you too.
