I use Ultrafractal 90% of the time and Apophysis the other 10% though I usually use multiple flames and compose them along with straight fractal layers in UF. Or, I'll use certain Apophysis flames as texture layers in UF. I used to use Winfract and Flarium24 "back in the day". I love the shapes in Xenodream and the vibrant colors in FE but, though I have those programs, I've not tried FE yet and XD just baffles one of my drastically limited cerebral capabilities. In other, more direct words: I'm dumb as a rock and stuck in a comfort zone! lol I keep telling myself I'm going to learn those "proggies" (as the Brits say - lol) but I'm always getting caught up in some project in UF that occupies me obsessively for days at a stretch till the wee hours. The time spent is of course closely related to the above mentioned lack of quality brain cells - lol Rick
