I have read many articles about Sweetex being used and seems to be highly rated basically. I haven't seen it here in my stores where I live ( Oklahoma City area). I would like to try it though but would prefer to go into an establishment locally to buy it rather than order online.
Try Midwest Bakers Supply: 2716 Nw 10th Street, Oklahoma City, OK 73107 405-942-3489. I've used the high-ratio shortening they carry, and it works great. Don't know the brand name, though.
