Well, obviously the Bee has more genetic potential with carrying 2 traits instead of just 1. But you already have Spider in your female, so no need to double-up on that. Are you planning to get more females? If so, I'd definitely go with the Bee, you can make some great things with them. But if you're just using your female Spider, then I'd go with the Cinny to shoot for Cinnabees and save a couple hundred bucks.
