I've been learning lunar salutations too, but I think I lean towards sun salutations because I'm more familiar with them.
Tonight, even though it's a little rainy outside, I practiced sun salutations. It felt great, especially the warmth that they create juxtaposed with the damp, chilled air.
A winter storm is supposed to be headed our way, and I look forward to the chance to practice to the sound of pounding rain. I think if I get that opportunity, I'll switch to lunar salutations and relish in the coolness they entice.
