I've finished Arnold's Prose Composition, but it's been a while, and I feel that I'm losing the knack for writing Latin, although I'm still reading quite a bit. But, again, I've been reading a lot of ML lately, which is great, but it doesn't exactly help me retain classical norms. So, I need a different composition textbook, but based on the same principle, preferably with grammar explanations and an answer key, but not beginner level. I think North & Hillard's will be good; is there anything else?Thanks for ideas!
