Icelandic Sheep in Texas?

Hello, I'm at the very beginning of my sheep research and I'm planning on getting my first flock in the next 2-5 years. I was looking at Icelandic sheep because I want to focus on regenerative farming and I read that they do very well on a mostly-pasture diet. I also like that they are seasonal breeders because I would like to keep the ram with them. My husband and I would use them mostly for meat but I would like to get a little milk just for our use. The fiber would also be a plus because I love to crochet and would like to learn how to spin yarn. It would be a small flock, probably around 10-12 after we get the hang of things. My question is, would Icelandic sheep do okay in a hot climate and would they be a good beginner breed? I'm not opposed to getting something different, this just looks to be the best on paper right now. Thank you for reading.
